Release Zulip Server 2.0.7.

Backported for 2.0.7 security release.

For a long time, we've been only doing the zxcvbn password strength
checks on the browser, which is helpful, but means users could through
hackery (or a bug in the frontend validation code) manage to set a
too-weak password.  We fix this by running our password strength
validation on the backend as well, using python-zxcvbn.

In theory, a bug in python-zxcvbn could result in it producing a
different opinion than the frontend version; if so, it'd be a pretty
bad bug in the library, and hopefully we'd hear about it from users,
report upstream, and get it fixed that way. Alternatively, we can
switch to shelling out to node like we do for KaTeX.

Fixes #6880.

We believe that the only sustainable model is for our core team to be compensated fairly for their time. We have thus founded a company (Kandra Labs) to steward and financially support Zulip’s development. We are growing our business sustainably, without venture capital funding. VCs are incentivized to push companies to gamble for explosive growth. Often, the result is that a company with a useful product burns rapidly through its resources and goes out of business. We have built Zulip as a sustainable business (also supported by SBIR grants from the US National Science Foundation), and are being thoughtful about our pace of spending. Funding our company without venture capital also allows us to live by our values, without investor pressure to compromise them when doing so might be “good business” or “what everyone does”.",

An important part of Zulip’s mission is ensuring that worthy organizations, from programming-language developers to research communities, are able to use Zulip whether or not they have funding. For this reason, we sponsor Zulip Cloud Standard for open source projects, non-profits, education, and academic research. This program has grown exponentially since its inception; today we are proud to fully sponsor Zulip hosting for several hundred organizations.

-## Moderating the Zulip community
-
-Anyone can help moderate the Zulip community by helping make sure that folks are
-aware of the [community guidelines](https://zulip.com/development-community/)
-and this Code of Conduct, and that we maintain a positive and respectful
-atmosphere.
-
-Here are some guidelines for you how can help:
-
-- Be friendly! Welcoming folks, thanking them for their feedback, ideas and effort,
-  and just trying to keep the atmosphere warm make the whole community function
-  more smoothly. New participants who feel accepted, listened to and respected
-  are likely to treat others the same way.
-
-- Be familiar with the [community
-  guidelines](https://zulip.com/development-community/), and cite them liberally
-  when a user violates them. Be polite but firm. Some examples:
-
-  - @user please note that there is no need to @-mention @\_**Tim Abbott** when
-    you ask a question. As noted in the [guidelines for this
-    community](https://zulip.com/development-community/):
-
-    > Use @-mentions sparingly… there is generally no need to @-mention a
-    > core contributor unless you need their timely attention.
-
-  - @user, please keep in mind the following [community
-    guideline](https://zulip.com/development-community/):
-
-    > Don’t ask the same question in multiple places. Moderators read every
-    > public stream, and make sure every question gets a reply.
-
-    I’ve gone ahead and moved the other copy of this message to this thread.
-
-  - If asked a question in a direct message that is better discussed in a public
-    stream:
-    > Hi @user! Please start by reviewing
-    > https://zulip.com/development-community/#community-norms to learn how to
-    > get help in this community.
-
-- Users sometimes think chat.zulip.org is a testing instance. When this happens,
-  kindly direct them to use the **#test here** stream.
-
-- If you see a message that’s posted in the wrong place, go ahead and move it if
-  you have permissions to do so, even if you don’t plan to respond to it.
-  Leaving the “Send automated notice to new topic” option enabled helps make it
-  clear what happened to the person who sent the message.
-
-  If you are responding to a message that's been moved, mention the user in your
-  reply, so that the mention serves as a notification of the new location for
-  their conversation.
-
-- If a user is posting spam, please report it to an administrator. They will:
-
-  - Change the user's name to `<name> (spammer)` and deactivate them.
-  - Delete any spam messages they posted in public streams.
-
-- We care very much about maintaining a respectful tone in our community. If you
-  see someone being mean or rude, point out that their tone is inappropriate,
-  and ask them to communicate their perspective in a respectful way in the
-  future. If you don’t feel comfortable doing so yourself, feel free to ask a
-  member of Zulip's core team to take care of the situation.
-
-- Try to assume the best intentions from others (given the range of
-  possibilities presented by their visible behavior), and stick with a friendly
-  and positive tone even when someone’s behavior is poor or disrespectful.
-  Everyone has bad days and stressful situations that can result in them
-  behaving not their best, and while we should be firm about our community
-  rules, we should also enforce them with kindness.

-Zulip uses GitHub for source control and code review, and becoming familiar with
-Git is essential for navigating and contributing to the Zulip codebase. [Our
-guide to Git](https://zulip.readthedocs.io/en/latest/git/index.html) will help
-you get started even if you've never used Git before.
+### Picking an issue
 
-If you're familiar with Git, you'll still want to take a look at [our
-Zulip-specific Git
-tools](https://zulip.readthedocs.io/en/latest/git/zulip-tools.html).
+Now, you're ready to pick your first issue! There are hundreds of open issues
+in the main codebase alone. This section will help you find an issue to work
+on.
 
-### Setting up your development environment and diving in
-
-To get started contributing code to Zulip, you will need to set up the
-development environment for the Zulip codebase you want to work on. You'll then
-want to take some time to familiarize yourself with the code.
-
-#### Server and web app
-
-1. [Install the development
-   environment](https://zulip.readthedocs.io/en/latest/development/overview.html).
-1. Familiarize yourself with [using the development
-   environment](https://zulip.readthedocs.io/en/latest/development/using.html).
-1. Go through the [new application feature
-   tutorial](https://zulip.readthedocs.io/en/latest/tutorials/new-feature-tutorial.html)
-   to get familiar with how the Zulip codebase is organized and how to find code
-   in it.
-
-#### Flutter-based mobile app
-
-1. Set up a development environment following the instructions in [the project
-   README](https://github.com/zulip/zulip-flutter).
-1. Start reading recent commits to see the code we're writing.
-   Use either a [graphical Git viewer][] like `gitk`, or `git log -p`
-   with [the "secret" to reading its output][git-log-secret].
-1. Pick some of the code that appears in those Git commits and that looks
-   interesting. Use your IDE to visit that code and to navigate to related code,
-   reading to see how it works and how the codebase is organized.

-#### Desktop app
-
-Follow [this
-documentation](https://github.com/zulip/zulip-desktop/blob/main/development.md)
-to set up the Zulip Desktop development environment.
-
-#### Terminal app

-## Finding an issue to work on
-
-### Where to look for an issue
-
-Now you're ready to pick your first issue! Zulip has several repositories you
-can check out, depending on your interests. There are hundreds of open issues in
-the [main Zulip server and web app
-repository](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
-alone.
-
-You can look through issues tagged with the "help wanted" label, which is used
-to indicate the issues that are open for contributions. You'll be able to claim
-unassigned issues, which you can find using the `no:assignee` filter in GitHub.
-You can also pick up issues that are assigned but are no longer being worked on.
-
-Some repositories use the "good first issue" label to tag issues that are
-especially approachable for new contributors.
-
-Here are some handy links for issues to look through:
-
-- [Server and web app](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
-- Mobile apps: no "help wanted" label, but see the
-  [project board](https://github.com/orgs/zulip/projects/5/views/4)
-  for the upcoming Flutter-based app. Look for issues up through the
-  "Launch" milestone, and that aren't already assigned.
-- [Desktop app](https://github.com/zulip/zulip-desktop/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
-- [Terminal app](https://github.com/zulip/zulip-terminal/issues?q=is%3Aopen+is%3Aissue+label%3A"help+wanted")
-- [Python API bindings and bots](https://github.com/zulip/python-zulip-api/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
-
-### Picking an issue to work on
-
-There's a lot to learn while making your first pull request, so start small!
-Many first contributions have fewer than 10 lines of changes (not counting
-changes to tests).
-
-We recommend the following process for finding an issue to work on:
-
-1. Find an issue tagged with the "help wanted" label that is either unassigned,
-   or looks to be abandoned.
-1. Read the description of the issue and make sure you understand it.
-1. If it seems promising, poke around the product
-   (on [chat.zulip.org](https://chat.zulip.org) or in the development
-   environment) until you know how the piece being
-   described fits into the bigger picture. If after some exploration the
-   description seems confusing or ambiguous, post a question on the GitHub
-   issue, as others may benefit from the clarification as well.
-1. When you find an issue you like, try to get started working on it. See if you
-   can find the part of the code you'll need to modify (`git grep` is your
-   friend!) and get some idea of how you'll approach the problem.
-1. If you feel lost, that's OK! Go through these steps again with another issue.
-   There's plenty to work on, and the exploration you do will help you learn
-   more about the project.
-
-An assigned issue can be considered abandoned if:
-
-- There is no recent contributor activity.
-- There are no open PRs, or an open PR needs work in order to be ready for
-  review. For example, a PR may need to be updated to address reviewer feedback
-  or to pass tests.
-
-Note that you are _not_ claiming an issue while you are iterating through steps
-1-4. _Before you claim an issue_, you should be confident that you will be able to
-tackle it effectively.
-
-Additional tips for the [main server and web app
-repository](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22):
-
-- We especially recommend browsing recently opened issues, as there are more
-  likely to be easy ones for you to find.
-- Take a look at issues with the ["good first issue"
-  label](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22),
-  as they are especially accessible to new contributors. However, you will
-  likely find issues without this label that are accessible as well.
-- All issues are partitioned into areas like
+* If you're interested in
+  [mobile](https://github.com/zulip/zulip-mobile/issues?q=is%3Aopen+is%3Aissue),
+  [desktop](https://github.com/zulip/zulip-electron/issues?q=is%3Aopen+is%3Aissue),
+  or
+  [bots](https://github.com/zulip/python-zulip-api/issues?q=is%3Aopen+is%3Aissue)
+  development, check the respective links for open issues, or post in
+  [#mobile](https://chat.zulip.org/#narrow/stream/48-mobile),
+  [#desktop](https://chat.zulip.org/#narrow/stream/16-desktop), or
+  [#integration](https://chat.zulip.org/#narrow/stream/127-integrations).
+* For the main server and web repository, start by looking through issues
+  with the label
+  [good first issue](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A"good+first+issue").
+  These are smaller projects particularly suitable for a first contribution.
+* We also partition all of our issues in the main repo into areas like
   admin, compose, emoji, hotkeys, i18n, onboarding, search, etc. Look
   through our [list of labels](https://github.com/zulip/zulip/labels), and
   click on some of the `area:` labels to see all the issues related to your
   areas of interest.
-- Avoid issues with the "difficult" label unless you
-  understand why it is difficult and are highly confident you can resolve the
-  issue correctly and completely.
+* If the lists of issues are overwhelming, post in
+  [#new members](https://chat.zulip.org/#narrow/stream/95-new-members) with a
+  bit about your background and interests, and we'll help you out. The most
+  important thing to say is whether you're looking for a backend (Python),
+  frontend (JavaScript), mobile (React Native), desktop (Electron),
+  documentation (English) or visual design (JavaScript + CSS) issue, and a
+  bit about your programming experience and available time.
 
-### Claiming an issue
+We also welcome suggestions of features that you feel would be valuable or
+changes that you feel would make Zulip a better open source project. If you
+have a new feature you'd like to add, we recommend you start by posting in
+[#new members](https://chat.zulip.org/#narrow/stream/95-new-members) with the
+feature idea and the problem that you're hoping to solve.
 
-#### In the main server/web app repository and Zulip Terminal repository
+Other notes:
+* For a first pull request, it's better to aim for a smaller contribution
+  than a bigger one. Many first contributions have fewer than 10 lines of
+  changes (not counting changes to tests).
+* The full list of issues looking for a contributor can be found with the
+  [good first issue](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22)
+  and
+  [help wanted](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
+  labels.
+* For most new contributors, there's a lot to learn while making your first
+  pull request. It's OK if it takes you a while; that's normal! You'll be
+  able to work a lot faster as you build experience.
 
-The Zulip server/web app repository
-([`zulip/zulip`](https://github.com/zulip/zulip/)) and the Zulip Terminal
-repository ([`zulip/zulip-terminal`](https://github.com/zulip/zulip-terminal/))
-are set up with a GitHub workflow bot called
-[Zulipbot](https://github.com/zulip/zulipbot), which manages issues and pull
-requests in order to create a better workflow for Zulip contributors.
+### Working on an issue
 
-To claim an issue in these repositories, simply post a comment that says
-`@zulipbot claim` to the issue thread. If the issue is [tagged with a help
-wanted label and is not assigned to someone
-else](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22+no%3Aassignee),
-Zulipbot will immediately assign the issue to you.
+To work on an issue, claim it by adding a comment with `@zulipbot claim` to
+the issue thread. [Zulipbot](https://github.com/zulip/zulipbot) is a GitHub
+workflow bot; it will assign you to the issue and label the issue as "in
+progress". Some additional notes:
 
-Note that new contributors can only claim one issue until their first pull request is
-merged. This is to encourage folks to finish ongoing work before starting
-something new. If you would like to pick up a new issue while waiting for review
-on an almost-ready pull request, you can post a comment to this effect on the
-issue you're interested in.
+* You can only claim issues with the
+  [good first issue](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22)
+  or
+  [help wanted](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
+  labels. Zulipbot will give you an error if you try to claim an issue
+  without one of those labels.
+* You're encouraged to ask questions on how to best implement or debug your
+  changes -- the Zulip maintainers are excited to answer questions to help
+  you stay unblocked and working efficiently. You can ask questions on
+  chat.zulip.org, or on the GitHub issue or pull request.
+* We encourage early pull requests for work in progress. Prefix the title of
+  work in progress pull requests with `[WIP]`, and remove the prefix when
+  you think it might be mergeable and want it to be reviewed.
+* After updating a PR, add a comment to the GitHub thread mentioning that it
+  is ready for another review. GitHub only notifies maintainers of the
+  changes when you post a comment, so if you don't, your PR will likely be
+  neglected by accident!
 
-#### In other Zulip repositories
+### And beyond
 
-There is no bot for other Zulip repositories
-([`zulip/zulip-flutter`](https://github.com/zulip/zulip-flutter/), etc.). If
-you are interested in claiming an issue in one of these repositories, simply
-post a comment on the issue thread saying that you've started work on the
-issue and would like to claim it. In your comment, describe what part of the
-code you're modifying and how you plan to approach the problem, based on
-what you learned in steps 1–4 [above](#picking-an-issue-to-work-on).
-
-There is no need to @-mention the issue creator in your comment. There is
-also no need to post the same information in multiple places, for example in
-a chat thread in addition to the GitHub issue.
-
-Please follow the same guidelines as described above: find an issue labeled
-"help wanted", and only pick up one issue at a time to start with.
-
-## Getting help
-
-You may have questions as you work on your pull request. For example, you might
-not be sure about some details of what's required, or have questions about your
-implementation approach. Zulip's maintainers are happy to answer thoughtfully
-posed questions, and discuss any difficulties that might arise as you work on
-your PR.
-
-If you haven't done so yet, now is the time to join the [Zulip development
-community](https://zulip.com/development-community/). If you'd like, introduce
-yourself in the [#new
-members](https://chat.zulip.org/#narrow/channel/95-new-members) channel, using
-your name as the [topic](https://zulip.com/help/introduction-to-topics).
-
-You can get help in public channels in the community:
-
-1. **Review** the [Zulip development community
-   guidelines](https://zulip.com/development-community/#community-norms).
-
-1. **Decide where to post.** If there is a discussion thread linked from the
-   issue you're working on, that's usually the best place to post any
-   clarification questions about the issue. Otherwise, follow [these
-   guidelines](https://zulip.com/development-community/#where-do-i-send-my-message)
-   to figure out where to post your question. Don’t stress too much about
-   picking the right place if you’re not sure, as moderators can [move your
-   question thread to a different
-   channel](https://zulip.com/help/move-content-to-another-channel) if needed.
-
-1. **Write** up your question, being sure to follow our [guide on asking great
-   questions](https://zulip.readthedocs.io/en/latest/contributing/asking-great-questions.html).
-   The guide explains what you need to do make sure that folks will be able to
-   help you out, and that you're making good use of maintainers' limited time.
-
-1. **Review** your message before you send it. Will your question make sense to
-   someone who is familiar with Zulip, but might not have the details of what
-   you are working on fresh in mind?
-
-Well-posed questions will generally get a response within 1-2 business days.
-There is no need to @-mention anyone when you ask a question, as maintainers
-keep a close eye on all the ongoing discussions.
-
-## What makes a great Zulip contributor?
-
-As you're working on your first code contribution, here are some best practices
-to keep in mind.
-
-- [Asking great questions][great-questions]. It's very hard to answer a general
-  question like, "How do I do this issue?" When asking for help, explain your
-  current understanding, including what you've done or tried so far and where
-  you got stuck. Post tracebacks or other error messages if appropriate. For
-  more advice, check out [our guide][great-questions]!
-- Learning and practicing
-  [Git commit discipline](https://zulip.readthedocs.io/en/latest/contributing/commit-discipline.html).
-- Submitting carefully tested code. See our [detailed guide on how to review
-  code](https://zulip.readthedocs.io/en/latest/contributing/code-reviewing.html#how-to-review-code)
-  (yours or someone else's).
-- Posting
-  [screenshots or GIFs](https://zulip.readthedocs.io/en/latest/tutorials/screenshot-and-gif-software.html)
-  for frontend changes.
-- Working to [make your pull requests easy to
-  review](https://zulip.readthedocs.io/en/latest/contributing/reviewable-prs.html).
-- Clearly describing what you have implemented and why. For example, if your
-  implementation differs from the issue description in some way or is a partial
-  step towards the requirements described in the issue, be sure to call
-  out those differences.
-- Being responsive to feedback on pull requests. This means incorporating or
-  responding to all suggested changes, and leaving a note if you won't be
-  able to address things within a few days.
-- Being helpful and friendly on the [Zulip community
-  server](https://zulip.com/development-community/).

-
-## Submitting a pull request
-
-See the [guide on submitting a pull
-request](https://zulip.readthedocs.io/en/latest/contributing/reviewable-prs.html)
-for detailed instructions on how to present your proposed changes to Zulip.
-
-The [pull request review process
-guide](https://zulip.readthedocs.io/en/latest/contributing/review-process.html)
-explains the stages of review your PR will go through, and offers guidance on
-how to help the review process move forward.
-
-It's OK if your first issue takes you a while; that's normal! You'll be able to
-work a lot faster as you build experience.
-
-## Beyond the first issue
-
-To find a second issue to work on, we recommend looking through issues with the same
+A great place to look for a second issue is to look for issues with the same
 `area:` label as the last issue you resolved. You'll be able to reuse the
 work you did learning how that part of the codebase works. Also, the path to
 becoming a core developer often involves taking ownership of one of these area
 labels.
 
-## Common questions
+## What makes a great Zulip contributor?
 
-- **What if somebody is already working on the issue I want to claim?** There
-  are lots of issues to work on (likely
-  [hundreds](https://github.com/zulip/zulip/issues?q=is%3Aissue%20state%3Aopen%20label%3A%22help%20wanted%22%20no%3Aassignee)
-  in the server repository)! If somebody else is actively working on the issue,
-  you can find a different one, or help with reviewing their work.
+Zulip runs a lot of [internship programs](#internship-programs), so we have
+a lot of experience with new contributors. In our experience, these are the
+best predictors of success:
 
-- **What if it looks like the person who's assigned an issue is no longer
-  working on it?** Post a comment on the issue, e.g., "Hi @ someone! Are you
-  still working on this one? I'd like to pick it up if not." You can pick up the
-  issue if they say they don't plan to work on it more.
+* Posting good questions. This generally means explaining your current
+  understanding, saying what you've done or tried so far, and including
+  tracebacks or other error messages if appropriate.
+* Learning and practicing
+  [Git commit discipline](https://zulip.readthedocs.io/en/latest/contributing/version-control.html#commit-discipline).
+* Submitting carefully tested code. This generally means checking your work
+  through a combination of automated tests and manually clicking around the
+  UI trying to find bugs in your work. See
+  [things to look for](https://zulip.readthedocs.io/en/latest/contributing/code-reviewing.html#things-to-look-for)
+  for additional ideas.
+* Posting
+  [screenshots or GIFs](https://zulip.readthedocs.io/en/latest/tutorials/screenshot-and-gif-software.html)
+  for frontend changes.
+* Being responsive to feedback on pull requests. This means incorporating or
+  responding to all suggested changes, and leaving a note if you won't be
+  able to address things within a few days.
+* Being helpful and friendly on chat.zulip.org.
 
-  - **What if I don't get a response?** If you don't get a reply within 2-3
-    days, go ahead and post a comment that you are working on the issue, and
-    submit a pull request. If the original assignee ends up submitting a pull
-    request first, no worries! You can help by providing feedback on their work,
-    or submit your own PR if you think a different approach is needed (as
-    described above).
+These are also the main criteria we use to select interns for all of our
+internship programs.
 
-- **What if there is already a pull request for the issue I want to work on?**
-  See our [guide on continuing unfinished
-  work](https://zulip.readthedocs.io/en/latest/contributing/continuing-unfinished-work.html).
+## Reporting issues
 
-- **What if somebody else claims an issue while I'm figuring out whether or not to
-  work on it?** No worries! You can contribute by providing feedback on
-  their pull request. If you've made good progress in understanding part of the
-  codebase, you can also find another "help wanted" issue in the same area to
-  work on.
+If you find an easily reproducible bug and/or are experienced in reporting
+bugs, feel free to just open an issue on the relevant project on GitHub.
 
-- **Can I work on an old issue?** Of course! Open issues marked as “help wanted”
-  are generally eligible to be worked on. If you find that the context around
-  the issue has changed (e.g., the UI looks different), do your best to apply
-  the current patterns, and comment on any differences from the spec in your PR
-  description.
+If you have a feature request or are not yet sure what the underlying bug
+is, the best place to post issues is
+[#issues](https://chat.zulip.org/#narrow/stream/9-issues) (or
+[#mobile](https://chat.zulip.org/#narrow/stream/48-mobile) or
+[#desktop](https://chat.zulip.org/#narrow/stream/16-desktop)) on the
+[Zulip community server](https://zulip.readthedocs.io/en/latest/contributing/chat-zulip-org.html).
+This allows us to interactively figure out what is going on, let you know if
+a similar issue has already been opened, and collect any other information
+we need. Choose a 2-4 word topic that describes the issue, explain the issue
+and how to reproduce it if known, your browser/OS if relevant, and a
+[screenshot or screenGIF](https://zulip.readthedocs.io/en/latest/tutorials/screenshot-and-gif-software.html)
+if appropriate.
 
-  If picking up a bug, start by checking if you can replicate it. If it no longer
-  replicates, post a comment on the issue explaining how you tested the
-  behavior, and what you saw, with screenshots as appropriate. And if you _can_
-  replicate it, fixing it is great!
+**Reporting security issues**. Please do not report security issues
+  publicly, including on public streams on chat.zulip.org. You can email
+  zulip-security@googlegroups.com. We create a CVE for every security issue.
 
-  If you're starting a major project where the issue was filed more than a
-  couple of years ago, it's a good idea to post to the development community
-  discussion thread for that issue to check if the thinking around it has
-  changed.
+## User feedback
 
-- **Can I come up with my own feature idea and work on it?** We welcome
-  suggestions of features or other improvements that you feel would be valuable. If you
-  have a new feature you'd like to add, you can start a conversation [in our
-  development community](https://zulip.com/development-community/#where-do-i-send-my-message)
-  explaining the feature idea and the problem that you're hoping to solve.
-- **I'm waiting for the next round of review on my PR. Can I pick up
-  another issue in the meantime?** Someone's first Zulip PR often
-  requires quite a bit of iteration, so please [make sure your pull
-  request is reviewable][reviewable-pull-requests] and go through at
-  least one round of feedback from others before picking up a second
-  issue. After that, sure! If
-  [Zulipbot](https://github.com/zulip/zulipbot) does not allow you to
-  claim an issue, you can post a comment describing the status of your
-  other work on the issue you're interested in (including links to all open
-  PRs), and asking for the issue to be assigned to you. Note that addressing
-  feedback on in-progress PRs should always take priority over starting a new
-  PR.
-- **I think my PR is done, but it hasn't been merged yet. What's going on?**
-  1. **Double-check that you have addressed all the feedback**, including any comments
-     on [Git commit
-     discipline](https://zulip.readthedocs.io/en/latest/contributing/commit-discipline.html),
-     and that automated tests are passing.
-  2. If all the feedback has been addressed, did you [leave a
-     comment](https://zulip.readthedocs.io/en/latest/contributing/review-process.html#how-to-help-move-the-review-process-forward)
-     explaining that you have done so and **requesting another review**? If not,
-     it may not be clear to project maintainers or reviewers that your PR is
-     ready for another look.
-  3. There may be a pause between initial rounds of review for your PR and final
-     review by project maintainers. This is normal, and we encourage you to **work
-     on other issues** while you wait.
-  4. If you think the PR is ready and haven't seen any updates for a couple
-     of weeks, it can be helpful to **leave another comment**. Summarize the
-     overall state of the review process and your work, and indicate that you
-     are waiting for a review.
-  5. Finally, **Zulip project maintainers are people too**! They may be busy
-     with other work, and sometimes they might even take a vacation. ;) It can
-     occasionally take a few weeks for a PR in the final stages of the review
-     process to be merged.
+Nearly every feature we develop starts with a user request. If you are part
+of a group that is either using or considering using Zulip, we would love to
+hear about your experience with the product. If you're not sure what to
+write, here are some questions we're always very curious to know the answer
+to:
 
-[reviewable-pull-requests]: https://zulip.readthedocs.io/en/latest/contributing/reviewable-prs.html
+* Evaluation: What is the process by which your organization chose or will
+  choose a group chat product?
+* Pros and cons: What are the pros and cons of Zulip for your organization,
+  and the pros and cons of other products you are evaluating?
+* Features: What are the features that are most important for your
+  organization? In the best case scenario, what would your chat solution do
+  for you?
+* Onboarding: If you remember it, what was your impression during your first
+  few minutes of using Zulip? What did you notice, and how did you feel? Was
+  there anything that stood out to you as confusing, or broken, or great?
+* Organization: What does your organization do? How big is the organization?
+  A link to your organization's website?
 
-## Outreach programs
+## Internship programs
 
-Zulip regularly participates in [Google Summer of Code
-(GSoC)](https://developers.google.com/open-source/gsoc/) and
-[Outreachy](https://www.outreachy.org/). We have been a GSoC mentoring
-organization since 2016, and we accept 15-20 GSoC participants each summer. In
-the past, we’ve also participated in [Google
-Code-In](https://developers.google.com/open-source/gci/), and hosted summer
-interns from Harvard, MIT, and Stanford.
+Zulip runs internship programs with
+[Outreachy](https://www.outreachy.org/),
+[Google Summer of Code (GSoC)](https://developers.google.com/open-source/gsoc/)
+[1], and the
+[MIT Externship program](https://alum.mit.edu/students/NetworkwithAlumni/ExternshipProgram),
+and has in the past taken summer interns from Harvard, MIT, and
+Stanford.
 
-Check out our [outreach programs
-overview](https://zulip.readthedocs.io/en/latest/outreach/overview.html) to learn
-more about participating in an outreach program with Zulip. Most of our program
-participants end up sticking around the project long-term, and many have become
-core team members, maintaining important parts of the project. We hope you
-apply!
+While each third-party program has its own rules and requirements, the
+Zulip community's approaches all of these programs with these ideas in
+mind:
+* We try to make the application process as valuable for the applicant as
+  possible. Expect high quality code reviews, a supportive community, and
+  publicly viewable patches you can link to from your resume, regardless of
+  whether you are selected.
+* To apply, you'll have to submit at least one pull request to a Zulip
+  repository.  Most students accepted to one of our programs have
+  several merged pull requests (including at least one larger PR) by
+  the time of the application deadline.
+* The main criteria we use is quality of your best contributions, and
+  the bullets listed at
+  [What makes a great Zulip contributor](#what-makes-a-great-zulip-contributor).
+  Because we focus on evaluating your best work, it doesn't hurt your
+  application to makes mistakes in your first few PRs as long as your
+  work improves.
+
+Zulip also participates in
+[Google Code-In](https://developers.google.com/open-source/gci/). Our
+selection criteria for Finalists and Grand Prize Winners is the same as our
+selection criteria for interns above.
+
+Most of our interns end up sticking around the project long-term, and many
+quickly become core team members. We hope you apply!
+
+### Google Summer of Code
+
+GSoC is by far the largest of our internship programs (we had 14 GSoC
+students in summer 2017).  While we don't control how many slots
+Google allocates to Zulip, we hope to mentor a similar number of
+students in 2018.
+
+If you're reading this well before the application deadline and want
+to make your application strong, we recommend getting involved in the
+community and fixing issues in Zulip now. Having good contributions
+and building a reputation for doing good work is best way to have a
+strong application.  About half of Zulip's GSoC students for Summer
+2017 had made significant contributions to the project by February
+2017, and about half had not.  Our
+[GSoC project ideas page][gsoc-guide] has lots more details on how
+Zulip does GSoC, as well as project ideas (though the project idea
+list is maintained only during the GSoC application period, so if
+you're looking at some other time of year, the project list is likely
+out-of-date).
+
+We also have in some past years run a Zulip Summer of Code (ZSoC)
+program for students who we didn't have enough slots to accept for
+GSoC but were able to find funding for.  Student expectations are the
+same as with GSoC, and it has no separate application process; your
+GSoC application is your ZSoC application.  If we'd like to select you
+for ZSoC, we'll contact you when the GSoC results are announced.
+
+[gsoc-guide]: https://zulip.readthedocs.io/en/latest/overview/gsoc-ideas.html
+[gsoc-faq]: https://developers.google.com/open-source/gsoc/faq
+
+[1] Formally, [GSoC isn't an internship][gsoc-faq], but it is similar
+enough that we're treating it as such for the purposes of this
+documentation.
+
+## Zulip Outreach
+
+**Upvoting Zulip**. Upvotes and reviews make a big difference in the public
+perception of projects like Zulip. We've collected a few sites below
+where we know Zulip has been discussed. Doing everything in the following
+list typically takes about 15 minutes.
+* Star us on GitHub. There are four main repositories:
+  [server/web](https://github.com/zulip/zulip),
+  [mobile](https://github.com/zulip/zulip-mobile),
+  [desktop](https://github.com/zulip/zulip-electron), and
+  [Python API](https://github.com/zulip/python-zulip-api).
+* [Follow us](https://twitter.com/zulip) on Twitter.
+
+For both of the following, you'll need to make an account on the site if you
+don't already have one.
+
+* [Like Zulip](https://alternativeto.net/software/zulip-chat-server/) on
+  AlternativeTo. We recommend upvoting a couple of other products you like
+  as well, both to give back to their community, and since single-upvote
+  accounts are generally given less weight. You can also
+  [upvote Zulip](https://alternativeto.net/software/slack/) on their page
+  for Slack.
+* [Add Zulip to your stack](https://stackshare.io/zulip) on StackShare, star
+  it, and upvote the reasons why people like Zulip that you find most
+  compelling. Again, we recommend adding a few other products that you like
+  as well.
+
+We have a doc with more detailed instructions and a few other sites, if you
+have been using Zulip for a while and want to contribute more.
+
+**Blog posts**. Writing a blog post about your experiences with Zulip, or
+about a technical aspect of Zulip can be a great way to spread the word
+about Zulip.
+
+We also occasionally [publish](http://blog.zulip.org/) longer form
+articles related to Zulip. Our posts typically get tens of thousands
+of views, and we always have good ideas for blog posts that we can
+outline but don't have time to write. If you are an experienced writer
+or copyeditor, send us a portfolio; we'd love to talk!

-    an existing row for the property/(realm, stream, user)/time with subgroup=None, Django would
-    create a duplicate row.
-
-    In the next migration, we'll add a proper constraint to fix this bug, but

-
-    We fix this in an appropriate fashion for each type of CountStat object; mainly

-An **API key** is how a bot identifies itself to Zulip. For the official
-clients, such as the Python bindings, we recommend [downloading a `zuliprc`
-file](/api/configuring-python-bindings#download-a-zuliprc-file). This file
-contains an API key and other necessary configuration values for using the
-Zulip API with a specific account on a Zulip server.

-
-These API client libraries make it easy to work with Zulip's REST API
-in your favorite language.
-
-## Official libraries
-
-These libraries are maintained by members of the Zulip core team.  The
-Python library is the most complete and best documented.
-
-* [Python](https://github.com/zulip/python-zulip-api)
-* [JavaScript](https://github.com/zulip/zulip-js)
-
-## User maintained libraries
-
-The Zulip core team doesn't have the resources to maintain
-high-quality libraries for every programming language.  We've
-collected a list of user-maintained libraries for popular languages:

-# Configuring the Python bindings
-
-Zulip provides a set of tools that allows interacting with its API more
-easily, called the [Python bindings](https://pypi.python.org/pypi/zulip/).
-One of the most notable use cases for these bindings are bots developed
-using Zulip's [bot framework](/api/writing-bots).
-
-In order to use them, you need to configure them with your identity
-(account, API key, and Zulip server URL). There are a few ways to
-achieve that:
-
-- Using a `zuliprc` file, referenced via the `--config-file` option or
-  the `config_file` option to the `zulip.Client` constructor
-  (recommended for bots).
-- Using a `zuliprc` file in your home directory at `~/.zuliprc`
-  (recommended for your own API key).
-- Using the [environment
-  variables](https://en.wikipedia.org/wiki/Environment_variable)
-  documented below.
-- Using the `--api-key`, `--email`, and `--site` variables as command
-  line parameters.
-- Using the `api_key`, `email`, and `site` parameters to the
-  `zulip.Client` constructor.
-
-## Download a `zuliprc` file
-
-{start_tabs}
-
-{tab|for-a-bot}
-
-{settings_tab|your-bots}
-
-1. Click the **download** (<i class="fa fa-download"></i>) icon on the profile
-   card of the desired bot to download the bot's `zuliprc` file.
-
-!!! warn ""
-
-    Anyone with a bot's API key can impersonate the bot, so be careful with it!
-
-{tab|for-yourself}
-
-{settings_tab|account-and-privacy}
-
-1. Under **API key**, click **Manage your API key**.
-
-1. Enter your password, and click **Get API key**. If you don't know your
-   password, click **reset it** and follow the
-   instructions from there.
-
-1. Click **Download zuliprc** to download your `zuliprc` file.
-
-1. (optional) If you'd like your credentials to be used by default
-   when using the Zulip API on your computer, move the `zuliprc` file
-   to `~/.zuliprc` in your home directory.
-
-!!! warn ""
-
-    Anyone with your API key can impersonate you, so be doubly careful with it.
-
-{end_tabs}
-
-## Configuration keys and environment variables
-
-`zuliprc` is a configuration file written in the
-[INI file format](https://en.wikipedia.org/wiki/INI_file),
-which contains key-value pairs as shown in the following example:
-
-```
-[api]
-key=<API key from the web interface>
-email=<your email address>
-site=<your Zulip server's URI>
-...
-```
-
-The keys you can use in this file (and their equivalent environment variables)
-can be found in the following table:

-# Construct a narrow
-
-A **narrow** is a set of filters for Zulip messages, that can be based
-on many different factors (like sender, channel, topic, search
-keywords, etc.). Narrows are used in various places in the Zulip
-API (most importantly, in the API for fetching messages).
-
-It is simplest to explain the algorithm for encoding a search as a
-narrow using a single example. Consider the following search query
-(written as it would be entered in the Zulip web app's search box).
-It filters for messages sent to channel `announce`, not sent by
-`iago@zulip.com`, and containing the words `cool` and `sunglasses`:
-
-```
-channel:announce -sender:iago@zulip.com cool sunglasses
-```
-
-This query would be JSON-encoded for use in the Zulip API using JSON
-as a list of simple objects, as follows:
-
-```json
-[
-    {
-        "operator": "channel",
-        "operand": "announce"
-    },
-    {
-        "operator": "sender",
-        "operand": "iago@zulip.com",
-        "negated": true
-    },
-    {
-        "operator": "search",
-        "operand": "cool sunglasses"
-    }
-]
-```
-
-The Zulip help center article on [searching for messages](/help/search-for-messages)
-documents the majority of the search/narrow options supported by the
-Zulip API.
-
-Note that many narrows, including all that lack a `channel` or `channels`
-operator, search the current user's personal message history. See
-[searching shared history](/help/search-for-messages#searching-shared-history)
-for details.
-
-Clients should note that the `is:unread` filter takes advantage of the
-fact that there is a database index for unread messages, which can be an
-important optimization when fetching messages in certain cases (e.g.,
-when [adding the `read` flag to a user's personal
-messages](/api/update-message-flags-for-narrow)).
-
-Note: When the value of `realm_empty_topic_display_name` found in
-the [POST /register](/api/register-queue) response is used as an operand
-for the `"topic"` operator in the narrow, it is interpreted
-as an empty string.
-
-## Changes
-
-* Before Zulip 10.0 (feature level 334), empty string was not a valid
-  topic name for channel messages.
-
-* In Zulip 9.0 (feature level 271), support was added for a new filter
-  operator, `with`, which uses a [message ID](#message-ids) for its
-  operand, and is designed for creating permanent links to topics.
-
-* In Zulip 9.0 (feature level 265), support was added for a new
-  `is:followed` filter, matching messages in topics that the current
-  user is [following](/help/follow-a-topic).
-
-* In Zulip 9.0 (feature level 250), support was added for two filters
-  related to stream messages: `channel` and `channels`. The `channel`
-  operator is an alias for the `stream` operator. The `channels`
-  operator is an alias for the `streams` operator. Both `channel` and
-  `channels` return the same exact results as `stream` and `streams`
-  respectively.
-
-* In Zulip 9.0 (feature level 249), support was added for a new filter,
-  `has:reaction`, which returns messages that have at least one [emoji
-  reaction](/help/emoji-reactions).
-
-* In Zulip 7.0 (feature level 177), support was added for three filters
-  related to direct messages: `is:dm`, `dm` and `dm-including`. The
-  `dm` operator replaced and deprecated the `pm-with` operator. The
-  `is:dm` filter replaced and deprecated the `is:private` filter. The
-  `dm-including` operator replaced and deprecated the `group-pm-with`
-  operator.
-
-    * The `dm-including` and `group-pm-with` operators return slightly
-      different results. For example, `dm-including:1234` returns all
-      direct messages (1-on-1 and group) that include the current user
-      and the user with the unique user ID of `1234`. On the other hand,
-      `group-pm-with:1234` returned only group direct messages that
-      included the current user and the user with the unique user ID of
-      `1234`.
-
-    * Both `dm` and `is:dm` are aliases of `pm-with` and `is:private`
-      respectively, and return the same exact results that the
-      deprecated filters did.
-
-## Narrows that use IDs
-
-### Message IDs
-
-The `id` and `with` operators use message IDs for their operands. The
-message ID operand for these two operators may be encoded as either a
-number or a string.
-
-* `id:12345`: Search for only the message with ID `12345`.
-* `with:12345`: Search for the conversation that contains the message
-  with ID `12345`.
-
-The `id` operator returns the message with the specified ID if it exists,
-and if it can be accessed by the user.
-
-The `with` operator is designed to be used for permanent links to
-topics, which means they should continue to work when the topic is
-[moved](/help/move-content-to-another-topic) or
-[resolved](/help/resolve-a-topic). If the message with the specified
-ID exists, and can be accessed by the user, then it will return
-messages with the `channel`/`topic`/`dm` operators corresponding to
-the current conversation containing that message, replacing any such
-operators included in the original narrow query.
-
-If no such message exists, or the message ID represents a message that
-is inaccessible to the user, this operator will be ignored (rather
-than throwing an error) if the remaining operators uniquely identify a
-conversation (i.e., they contain `channel` and `topic` terms or `dm`
-term). This behavior is intended to provide the best possible
-experience for links to private channels with protected history.
-
-The [help center](/help/search-for-messages#search-by-message-id) also
-documents the `near` operator for searching for messages by ID, but
-this narrow operator has no effect on filtering messages when sent to
-the server. In practice, when the `near` operator is used to search for
-messages, or is part of a URL fragment, the value of its operand should
-instead be used for the value of the `anchor` parameter in endpoints
-that also accept a `narrow` parameter; see
-[GET /messages][anchor-get-messages] and
-[POST /messages/flags/narrow][anchor-post-flags].
-
-**Changes**: Prior to Zulip 8.0 (feature level 194), the message ID
-operand for the `id` operator needed to be encoded as a string.
-
-
-```json
-[
-    {
-        "operator": "id",
-        "operand": 12345
-    }
-]
-```
-
-### Channel and user IDs
-
-There are a few additional narrow/search options (new in Zulip 2.1)
-that use either channel IDs or user IDs that are not documented in the
-help center because they are primarily useful to API clients:
-
-* `channel:1234`: Search messages sent to the channel with ID `1234`.
-* `sender:1234`: Search messages sent by user ID `1234`.
-* `dm:1234`: Search the direct message conversation between
-  you and user ID `1234`.
-* `dm:1234,5678`: Search the direct message conversation between
-  you, user ID `1234`, and user ID `5678`.
-* `dm-including:1234`: Search all direct messages (1-on-1 and group)
-  that include you and user ID `1234`.
-
-!!! tip ""
-
-    A user ID can be found by [viewing a user's profile][view-profile]
-    in the web or desktop apps. A channel ID can be found when [browsing
-    channels][browse-channels] in the web or desktop apps.
-
-The operands for these search options must be encoded either as an
-integer ID or a JSON list of integer IDs. For example, to query
-messages sent by a user 1234 to a direct message thread with yourself,
-user 1234, and user 5678, the correct JSON-encoded query is:
-
-```json
-[
-    {
-        "operator": "dm",
-        "operand": [1234, 5678]
-    },
-    {

-# Deploying bots in production
-
-Usually, work on a bot starts on a laptop.  At some point, you'll want
-to deploy your bot in a production environment, so that it'll stay up
-regardless of what's happening with your laptop.  There are several
-options for doing so:
-
-* The simplest is running `zulip-run-bot` inside a `screen` session on
-  a server.  This works, but if your server reboots, you'll need to
-  manually restart it, so we don't recommend it.
-* Using `supervisord` or a similar tool for managing a production
-  process with `zulip-run-bot`.  This consumes a bit of resources
-  (since you need a persistent process running), but otherwise works
-  great.
-* Using the Zulip Botserver, which is a simple Flask server for
-  running a bot in production, and connecting that to Zulip's outgoing
-  webhooks feature.  This can be deployed in environments like
-  Heroku's free tier without running a persistent process.
-
-## Zulip Botserver
-
-The Zulip Botserver is for people who want to
-
-* run bots in production.
-* run multiple bots at once.
-
-The Zulip Botserver is a Python (Flask) server that implements Zulip's
-outgoing webhooks API.  You can of course write your own servers using
-the outgoing webhooks API, but the Botserver is designed to make it
-easy for a novice Python programmer to write a new bot and deploy it
-in production.
-
-### How Botserver works
-
-Zulip Botserver starts a web server that listens to incoming messages
-from your main Zulip server. The sequence of events in a successful
-Botserver interaction are:
-
-1. Your bot user is mentioned or receives a direct message:
-
-    ```
-    @**My Bot User** hello world
-    ```
-
-1. The Zulip server sends a POST request to the Botserver on `https://bot-server.example.com/`:
-
-    ```
-    {
-      "message":{
-        "content":"@**My Bot User** hello world",
-      },
-      "bot_email":"myuserbot-bot@example.com",
-      "trigger":"mention",
-      "token":"XXXX"
-    }
-    ```
-
-    This URL is configured in the Zulip web-app in your Bot User's settings.
-
-1. The Botserver searches for a bot to handle the message, and executes your
-   bot's `handle_message` code.
-
-Your bot's code should work just like it does with `zulip-run-bot`;
-for example, you reply using
-[bot_handler.send_reply](writing-bots#bot_handlersend_reply)).
-
-### Installing the Zulip Botserver
-
-Install the `zulip_botserver` package:
-
-```
-pip3 install zulip_botserver
-```
-
-### Running a bot using the Zulip Botserver
-
-{start_tabs}
-
-1. Construct the URL for your bot, which will be of the form:
-
-    ```
-    http://<hostname>:<port>
-    ```
-
-    where the `hostname` is the hostname you'll be running the bot
-    server on, and `port` is the port for it (the recommended default
-    is `5002`).
-
-1. Register new bot users on the Zulip server's web interface.
-
-    * Log in to the Zulip server.
-    * Navigate to *Personal settings (<i class="zulip-icon zulip-icon-gear"></i>)* -> *Bots* -> *Add a new bot*.
-      Select *Outgoing webhook* for bot type, fill out the form (using
-      the URL from above) and click on *Create bot*.
-    * A new bot user should appear in the *Active bots* panel.
-
-1. Download the `zuliprc` file for your bot from the *Active Bots*
-   panel, using the download button.
-
-1. Run the Botserver, where `helloworld` is the name of the bot you
-   want to run:
-
-    `zulip-botserver --config-file <path_to_zuliprc> --bot-name=helloworld`
-
-    You can specify the port number and various other options; run
-    `zulip-botserver --help` to see how to do this.
-
-1.  Congrats, everything is set up! Test your Botserver like you would
-    test a normal bot.
-
-{end_tabs}
-
-### Running multiple bots using the Zulip Botserver
-
-The Zulip Botserver also supports running multiple bots from a single
-Botserver process.  You can do this with the following procedure.
-
-{start_tabs}
-
-1. Download the `botserverrc` from the `your-bots` settings page, using
-   the "Download config of all active outgoing webhook bots in Zulip
-   Botserver format." option at the top.
-
-1. Open the `botserverrc`. It should contain one or more sections that look like this:
-
-    ```
-    []
-    email=foo-bot@hostname
-    key=dOHHlyqgpt5g0tVuVl6NHxDLlc9eFRX4
-    site=http://hostname
-    token=aQVQmSd6j6IHphJ9m1jhgHdbnhl5ZcsY
-    ```
-
-    Each section contains the configuration for an outgoing webhook bot. For each
-    bot, enter the name of the bot you want to run in the square brackets `[]`.
-    For example, if we want `foo-bot@hostname` to run the `helloworld` bot, our
-    new section would look like this:
-
-    ```
-    [helloworld]
-    email=foo-bot@hostname
-    key=dOHHlyqgpt5g0tVuVl6NHxDLlc9eFRX4
-    site=http://hostname
-    token=aQVQmSd6j6IHphJ9m1jhgHdbnhl5ZcsY
-    ```
-
-    To run an external bot, enter the path to the bot's python file in the square
-    brackets `[]`. For example, if we want to run `~/Documents/my_new_bot.py`, our
-    new section could look like this:
-
-    ```
-    [~/Documents/my_new_bot.py]
-    email=foo-bot@hostname
-    key=dOHHlyqgpt5g0tVuVl6NHxDLlc9eFRX4
-    site=http://hostname
-    ```
-
-1.  Run the Zulip Botserver by passing the `botserverrc` to it. The
-    command format is:
-
-     ```
-     zulip-botserver  --config-file <path_to_botserverrc>
-     ```
-
-     If omitted, `hostname` defaults to `127.0.0.1` and `port` to `5002`.
-
-{end_tabs}
-
-### Running Zulip Botserver with supervisord
-
-[supervisord](http://supervisord.org/) is a popular tool for running
-services in production.  It helps ensure the service starts on boot,
-manages log files, restarts the service if it crashes, etc.  This
-section documents how to run the Zulip Botserver using *supervisord*.
-
-Running the Zulip Botserver with *supervisord* works almost like
-running it manually.
-
-{start_tabs}
-
-1.  Install *supervisord* via your package manager; e.g., on Debian/Ubuntu:
-
-     ```
-     sudo apt-get install supervisor
-     ```
-
-1.  Configure *supervisord*.  *supervisord* stores its configuration in
-    `/etc/supervisor/conf.d`.
-    * Do **one** of the following:
-      * Download the [sample config file][supervisord-config-file]
-        and store it in `/etc/supervisor/conf.d/zulip-botserver.conf`.
-      * Copy the following section into your existing supervisord config file.
-
-            [program:zulip-botserver]
-            command=zulip-botserver --config-file=<path/to/your/botserverrc>
-            --hostname <address> --port <port>
-            startsecs=3
-            stdout_logfile=/var/log/zulip-botserver.log ; all output of your Botserver will be logged here
-            redirect_stderr=true
-
-    * Edit the `<>` sections according to your preferences.
-
-[supervisord-config-file]: https://raw.githubusercontent.com/zulip/python-zulip-api/main/zulip_botserver/zulip-botserver-supervisord.conf
-
-1. Update *supervisord* to read the configuration file:
-
-    ```
-    supervisorctl reread
-    supervisorctl update
-    ```
-
-    (or you can use `/etc/init.d/supervisord restart`, but this is less
-    disruptive if you're using *supervisord* for other services as well).
-
-1. Test if your setup is successful:
-
-    ```
-    supervisorctl status
-    ```
-
-    The output should include a line similar to this:
-    > zulip-botserver                 RUNNING   pid 28154, uptime 0:00:27
-
-    The standard output of the Botserver will be logged to the path in
-    your *supervisord* configuration.
-
-{end_tabs}
-
-If you are hosting the Botserver yourself (as opposed to using a
-hosting service that provides SSL), we recommend securing your
-Botserver with SSL using an `nginx` or `Apache` reverse proxy and
-[Certbot](https://certbot.eff.org/).
-
-### Troubleshooting
-
-- Make sure the API key you're using is for an [outgoing webhook
-  bot](/api/outgoing-webhooks) and you've
-  correctly configured the URL for your Botserver.
-
-- Your Botserver needs to be accessible from your Zulip server over
-  HTTP(S).  Make sure any firewall allows the connection.  We
-  recommend using [zulip-run-bot](running-bots) instead for
-  development/testing on a laptop or other non-server system.
-  If your Zulip server is self-hosted, you can test by running `curl
-  http://zulipbotserver.example.com:5002` from your Zulip server;
-  the output should be:
-
-    ```
-    $ curl http://zulipbotserver.example.com:5002/
-    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
-    <title>405 Method Not Allowed</title>
-    <h1>Method Not Allowed</h1>
-    <p>The method is not allowed for the requested URL.</p>
-    ```

-# Group-setting values
-
-Settings defining permissions in Zulip are increasingly represented
-using [user groups](/help/user-groups), which offer much more flexible
-configuration than the older [roles](/api/roles-and-permissions) system.
-
-!!! warn ""
-
-    **Note**: Many group-valued settings are configured to require
-    a single system group for their value via
-    `server_supported_permission_settings`, pending web app UI
-    changes to fully support group-setting values.
-
-    **Changes**: Before Zulip 10.0 (feature level 309), only system
-    groups were permitted values for group-setting values in
-    production environments, regardless of the values in
-    `server_supported_permission_settings`.
-
-In the API, these settings are represented using a **group-setting
-value**, which can take two forms:
-
-- An integer user group ID, which can be either a named user group
-  visible in the UI or a [role-based system group](#system-groups).
-- An object with fields `direct_member_ids`, containing a list of
-  integer user IDs, and `direct_subgroup_ids`, containing a list of
-  integer group IDs. The setting's value is the union of the
-  identified collection of users and groups.
-
-Group-setting values in the object form can be thought of as an
-anonymous group. They function very much like a named user group
-object, and remove the naming and UI overhead involved in creating
-a visible user group just to store the value of a single setting.
-
-The server will canonicalize an object with an empty `direct_member_ids`
-list and a `direct_subgroup_ids` list that contains just a single group
-ID to the integer format.
-
-## System groups
-
-The Zulip server maintains a collection of system groups that
-correspond to the users with a given role; this makes it convenient to
-store concepts like "all administrators" in a group-setting
-value. These use a special naming convention and can be recognized by
-the `is_system_group` property on their group object.
-
-The following system groups are maintained by the Zulip server:
-
-- `role:internet`: Everyone on the Internet has this permission; this
-  is used to configure the [public access
-  option](/help/public-access-option).
-- `role:everyone`: All users, including guests.
-- `role:members`: All users, excluding guests.
-- `role:fullmembers`: All [full
-  members](https://zulip.com/api/roles-and-permissions#determining-if-a-user-is-a-full-member)
-  of the organization.
-- `role:moderators`: All users with at least the moderator role.
-- `role:administrators`: All users with at least the administrator
-  role.
-- `role:owners`: All users with the owner role.
-- `role:nobody`: The formal empty group. Used in the API to represent
-  disabling a feature.
-
-Client UI for setting a permission or displaying a group (when
-silently mentioned, for example) is encouraged to display system
-groups using their description, rather than using their `role:}`
-names, which are chosen to be unique and clear in the API.
-
-System groups should generally not be displayed in UI for
-administering an organization's user groups, since they are not
-directly mutable.
-
-## Updating group-setting values
-
-The Zulip API uses a special format for modifying an existing setting
-using a group-setting value.
-
-A **group-setting update** is an object with a `new` field and an
-optional `old` field, each containing a group-setting value. The
-setting's value will be set to the membership expressed by the `new`
-field.
-
-The `old` field expresses the client's understanding of the current
-value of the setting. If the `old` field is present and does not match
-the actual current value of the setting, then the request will fail
-with error code `EXPECTATION_MISMATCH` and no changes will be applied.
-
-When a user edits the setting in a UI, the resulting API request
-should generally always include the `old` field, giving the value
-the list had when the user started editing. This accurately expresses
-the user's intent, and if two users edit the same list around the
-same time, it prevents a situation where the second change
-accidentally reverts the first one without either user noticing.
-
-Omitting `old` is appropriate where the intent really is a new complete
-list rather than an edit, for example in an integration that syncs the
-list from an external source of truth.
-
-## Permitted values
-
-Not every possible group-setting value is a valid configuration for a
-given group-based setting. For example, as a security hardening
-measure, some administrative permissions should never be exercised by
-guest users, and the system group for all users, including guests,
-should not be offered to users as an option for those settings.
-
-Others have restrictions to only permit system groups due to UI
-components not yet having been migrated to support a broader set of
-values. In order to avoid this configuration ending up hardcoded in
-clients, every permission setting using this framework has an entry in
-the `server_supported_permission_settings` section of the [`POST
-/register`](/api/register-queue) response.
-
-Clients that support mutating group-settings values must parse that
-part of the `register` payload in order to compute the set of
-permitted values to offer to the user and avoid server-side errors
-when trying to save a value.
-
-Note specifically that the `allow_everyone_group` field, which
-determines whether the setting can have the value of "all user
-accounts, including guests" also controls whether guests users can
-exercise the permission regardless of their membership in the
-group-setting value.

api_docs/http-headers.md

-# HTTP headers
-
-This page documents the HTTP headers used by the Zulip API.
-
-Most important is that API clients authenticate to the server using
-HTTP Basic authentication. If you're using the official [Python or
-JavaScript bindings](/api/installation-instructions), this is taken
-care of when you configure said bindings.
-
-Otherwise, see the `curl` example on each endpoint's documentation
-page, which details the request format.
-
-Documented below are additional HTTP headers and header conventions
-generally used by Zulip:
-
-## The `User-Agent` header
-
-Clients are not required to pass a `User-Agent` HTTP header, but we
-highly recommend doing so when writing an integration. It's easy to do
-and it can help save time when debugging issues related to an API
-client.
-
-If provided, the Zulip server will parse the `User-Agent` HTTP header
-in order to identify specific clients and integrations. This
-information is used by the server for logging, [usage
-statistics](/help/analytics), and on rare occasions, for
-backwards-compatibility logic to preserve support for older versions
-of official clients.
-
-Official Zulip clients and integrations use a `User-Agent` that starts
-with something like `ZulipMobile/20.0.103 `, encoding the name of the
-application and it's version.
-
-Zulip's official API bindings have reasonable defaults for
-`User-Agent`. For example, the official Zulip Python bindings have a
-default `User-Agent` starting with `ZulipPython/{version}`, where
-`version` is the version of the library.
-
-You can give your bot/integration its own name by passing the `client`
-parameter when initializing the Python bindings. For example, the
-official Zulip Nagios integration is initialized like this:
-
-``` python
-client = zulip.Client(
-    config_file=opts.config, client=f"ZulipNagios/{VERSION}"
-)
-```
-
-If you are working on an integration that you plan to share outside
-your organization, you can get help picking a good name in
-`#integrations` in the [Zulip development
-community](https://zulip.com/development-community/).
-
-## Rate-limiting response headers
-
-To help clients avoid exceeding rate limits, Zulip sets the following
-HTTP headers in all API responses:
-
-* `X-RateLimit-Remaining`: The number of additional requests of this
-  type that the client can send before exceeding its limit.
-* `X-RateLimit-Limit`: The limit that would be applicable to a client
-  that had not made any recent requests of this type. This is useful
-  for designing a client's burst behavior so as to avoid ever reaching
-  a rate limit.
-* `X-RateLimit-Reset`: The time at which the client will no longer
-  have any rate limits applied to it (and thus could do a burst of
-  `X-RateLimit-Limit` requests).
-
-[Zulip's rate limiting rules are configurable][rate-limiting-rules],
-and can vary by server and over time. The default configuration
-currently limits:
-
-* Every user is limited to 200 total API requests per minute.
-* Separate, much lower limits for authentication/login attempts.
-
-When the Zulip server has configured multiple rate limits that apply
-to a given request, the values returned will be for the strictest
-limit.

-# Incoming webhook integrations
-
-An incoming webhook allows a third-party service to push data to Zulip when
-something happens. There are several ways to set up an incoming webhook in
-Zulip:
-
-* Use our [REST API](/api/rest) endpoint for [sending
-  messages](/api/send-message).  This works great for internal tools
-  or cases where the third-party tool wants to control the formatting
-  of the messages in Zulip.
-* Use one of our supported [integration
-  frameworks](/integrations/meta-integration), such as the
-  [Slack-compatible incoming webhook](/integrations/doc/slack_incoming),
-  [Zapier integration](/integrations/doc/zapier), or
-  [IFTTT integration](/integrations/doc/ifttt).
-* Implementing an incoming webhook integration (detailed on this page),
-  where all the logic for formatting the Zulip messages lives in the
-  Zulip server.  This is how most of [Zulip's official
-  integrations](/integrations/) work, because they enable Zulip to
-  support third-party services that just have an "outgoing webhook"
-  feature (without the third party needing to do any work specific to
-  Zulip).
-
-In an incoming webhook integration, the third-party service's
-"outgoing webhook" feature sends an `HTTP POST` to a special URL when
-it has something for you, and then the Zulip "incoming webhook"
-integration handles that incoming data to format and send a message in
-Zulip.
-
-New official Zulip webhook integrations can take just a few hours to
-write, including tests and documentation, if you use the right
-process.
-
-## Quick guide
-
-* Set up the
-  [Zulip development environment](https://zulip.readthedocs.io/en/latest/development/overview.html).
-
-* Use [Zulip's JSON integration](/integrations/doc/json),
-  <https://webhook.site/>, or a similar site to capture an example
-  webhook payload from the third-party service. Create a
-  `zerver/webhooks/<mywebhook>/fixtures/` directory, and add the
-  captured JSON payload as a test fixture.
-
-* Create an `Integration` object, and add it to the `WEBHOOK_INTEGRATIONS`
-  list in `zerver/lib/integrations.py`. Search for `WebhookIntegration` in that
-  file to find an existing one to copy.
-
-* Write a draft webhook handler in `zerver/webhooks/<mywebhook>/view.py`. There
-  are a lot of examples in the `zerver/webhooks/` directory that you can copy.
-  We recommend templating from a short one, like `zendesk`.
-
-* Write a test for your fixture in `zerver/webhooks/<mywebhook>/tests.py`.
-  Run the test for your integration like this:
-
-    ```
-    tools/test-backend zerver/webhooks/<mywebhook>/
-    ```
-
-    Iterate on debugging the test and webhooks handler until it all
-    works.
-
-* Capture payloads for the other common types of `POST`s the third-party
-  service will make, and add tests for them; usually this part of the
-  process is pretty fast.
-
-* Document the integration in `zerver/webhooks/<mywebhook>/doc.md`(required for
-  getting it merged into Zulip). You can use existing documentation, like
-  [this one](https://raw.githubusercontent.com/zulip/zulip/main/zerver/webhooks/github/doc.md),
-  as a template. This should not take more than 15 minutes, even if you don't speak English
-  as a first language (we'll clean up the text before merging).
-
-## Hello world walkthrough
-
-Check out the [detailed walkthrough](incoming-webhooks-walkthrough) for step-by-step
-instructions.
-
-## Checklist
-
-### Files that need to be created
-
-Select a name for your incoming webhook and use it consistently. The examples
-below are for a webhook named `MyWebHook`.
-
-* `zerver/webhooks/mywebhook/__init__.py`: Empty file that is an obligatory
-   part of every python package.  Remember to `git add` it.
-* `zerver/webhooks/mywebhook/view.py`: The main webhook integration function,
-  called `api_mywebhook_webhook`, along with any necessary helper functions.
-* `zerver/webhooks/mywebhook/fixtures/message_type.json`: Sample JSON payload data
-  used by tests. Add one fixture file per type of message supported by your
-  integration.
-* `zerver/webhooks/mywebhook/tests.py`: Tests for your webhook.
-* `zerver/webhooks/mywebhook/doc.md`: End-user documentation explaining
-  how to add the integration.
-* `static/images/integrations/logos/mywebhook.svg`: A square logo for the
-  platform/server/product you are integrating. Used on the documentation
-  pages as well as the sender's avatar for messages sent by the integration.
-* `static/images/integrations/mywebhook/001.png`: A screenshot of a message
-  sent by the integration, used on the documentation page. This can be
-  generated by running `tools/screenshots/generate-integration-docs-screenshot --integration mywebhook`.
-* `static/images/integrations/bot_avatars/mywebhook.png`: A square logo for the
-  platform/server/product you are integrating which is used to create the avatar
-  for generating screenshots with. This can be generated automatically from
-  `static/images/integrations/logos/mywebhook.svg` by running
-  `tools/setup/generate_integration_bots_avatars.py`.
-
-### Files that need to be updated
-
-* `zerver/lib/integrations.py`: Add your integration to
-  `WEBHOOK_INTEGRATIONS`. This will automatically register a
-  URL for the incoming webhook of the form `api/v1/external/mywebhook` and
-  associate it with the function called `api_mywebhook_webhook` in
-  `zerver/webhooks/mywebhook/view.py`. Also add your integration to
-  `DOC_SCREENSHOT_CONFIG`. This will allow you to automatically generate
-  a screenshot for the documentation by running
-  `tools/screenshots/generate-integration-docs-screenshot --integration mywebhook`.
-
-## Common Helpers
-
-* If your integration will receive a test webhook payload, you can use
-  `get_setup_webhook_message` to create our standard message for test payloads.
-  You can import this from `zerver/lib/webhooks/common.py`, and it will generate
-  a message like this: "GitHub webhook is successfully configured! 🎉"
-
-## General advice
-
-* Consider using our Zulip markup to make the output from your
-  integration especially attractive or useful (e.g., emoji, Markdown
-  emphasis, or @-mentions).
-
-* Use topics effectively to ensure sequential messages about the same
-  thing are threaded together; this makes for much better consumption
-  by users.  E.g., for a bug tracker integration, put the bug number in
-  the topic for all messages; for an integration like Nagios, put the
-  service in the topic.
-
-* Integrations that don't match a team's workflow can often be
-  uselessly spammy.  Give careful thought to providing options for
-  triggering Zulip messages only for certain message types, certain
-  projects, or sending different messages to different channels/topics,
-  to make it easy for teams to configure the integration to support
-  their workflow.
-
-* Consistently capitalize the name of the integration in the
-  documentation and the Client name the way the vendor does.  It's OK
-  to use all-lower-case in the implementation.
-
-* Sometimes it can be helpful to contact the vendor if it appears they
-  don't have an API or webhook we can use; sometimes the right API
-  is just not properly documented.
-
-* A helpful tool for testing your integration is
-  [UltraHook](http://www.ultrahook.com/), which allows you to receive webhook
-  calls via your local Zulip development environment. This enables you to do end-to-end
-  testing with live data from the service you're integrating and can help you
-  spot why something isn't working or if the service is using custom HTTP
-  headers.
-
-## URL specification
-
-The base URL for an incoming webhook integration bot, where
-`INTEGRATION_NAME` is the name of the specific webhook integration and
-`API_KEY` is the API key of the bot created by the user for the
-integration, is:
-
-```
-{{ api_url }}/v1/external/INTEGRATION_NAME?api_key=API_KEY
-```
-
-The list of existing webhook integrations can be found by browsing the
-[Integrations documentation](/integrations/) or in
-`zerver/lib/integrations.py` at `WEBHOOK_INTEGRATIONS`.
-
-Parameters accepted in the URL include:
-
-### api_key *(required)*
-
-The API key of the bot created by the user for the integration. To get a
-bot's API key, see the [API keys](/api/api-keys) documentation.
-
-### stream
-
-The channel for the integration to send notifications to. Can be either
-the channel ID or the [URL-encoded][url-encoder] channel name. By default
-the integration will send direct messages to the bot's owner.
-
-!!! tip ""
-
-    A channel ID can be found when [browsing channels][browse-channels]
-    in the web or desktop apps.
-
-### topic
-
-The topic in the specified channel for the integration to send
-notifications to. The topic should also be [URL-encoded][url-encoder].
-By default the integration will have a topic configured for channel
-messages.
-
-### only_events, exclude_events
-
-Some incoming webhook integrations support these parameters to filter
-which events will trigger a notification. You can append either
-`&only_events=["event_a","event_b"]` or
-`&exclude_events=["event_a","event_b"]` (or both, with different events)
-to the URL, with an arbitrary number of supported events.
-
-You can use UNIX-style wildcards like `*` to include multiple events.
-For example, `test*` matches every event that starts with `test`.
-
-!!! tip ""
-
-    For a list of supported events, see a specific [integration's
-    documentation](/integrations) page.

-# Incoming webhook walkthrough
-
-Below, we explain each part of a simple incoming webhook integration,
-called **Hello World**.  This integration sends a "hello" message to the `test`
-channel and includes a link to the Wikipedia article of the day, which
-it formats from json data it receives in the http request.
-
-Use this walkthrough to learn how to write your first webhook
-integration.
-
-## Step 0: Create fixtures
-
-The first step in creating an incoming webhook is to examine the data that the
-service you want to integrate will be sending to Zulip.
-
-* Use [Zulip's JSON integration](/integrations/doc/json),
-<https://webhook.site/>, or a similar tool to capture webhook
-payload(s) from the service you are integrating. Examining this data
-allows you to do two things:
-
-1. Determine how you will need to structure your webhook code, including what
-   message types your integration should support and how.
-2. Create fixtures for your webhook tests.
-
-A test fixture is a small file containing test data, one for each test.
-Fixtures enable the testing of webhook integration code without the need to
-actually contact the service being integrated.
-
-Because `Hello World` is a very simple integration that does one
-thing, it requires only one fixture,
-`zerver/webhooks/helloworld/fixtures/hello.json`:
-
-```json
-{
-  "featured_title":"Marilyn Monroe",
-  "featured_url":"https://en.wikipedia.org/wiki/Marilyn_Monroe",
-}
-```
-
-When writing your own incoming webhook integration, you'll want to write a test function
-for each distinct message condition your integration supports. You'll also need a
-corresponding fixture for each of these tests. Depending on the type of data
-the 3rd party service sends, your fixture may contain JSON, URL encoded text, or
-some other kind of data. See [Step 5: Create automated tests](#step-5-create-automated-tests) or
-[Testing](https://zulip.readthedocs.io/en/latest/testing/testing.html) for further details.
-
-### HTTP Headers
-
-Some third-party webhook APIs, such as GitHub's, don't encode all the
-information about an event in the JSON request body.  Instead, they
-put key details like the event type in a separate HTTP header
-(generally this is clear in their API documentation).  In order to
-test Zulip's handling of that integration, you will need to record
-which HTTP headers are used with each fixture you capture.
-
-Since this is integration-dependent, Zulip offers a simple API for
-doing this, which is probably best explained by looking at the example
-for GitHub: `zerver/webhooks/github/view.py`; basically, as part of
-writing your integration, you'll write a special function in your
-view.py file that maps the filename of the fixture to the set of HTTP
-headers to use. This function must be named "fixture_to_headers". Most
-integrations will use the same strategy as the GitHub integration:
-encoding the third party variable header data (usually just an event
-type) in the fixture filename, in such a case, you won't need to
-explicitly write the logic for such a special function again,
-instead you can just use the same helper method that the GitHub
-integration uses.
-
-## Step 1: Initialize your webhook python package
-
-In the `zerver/webhooks/` directory, create new subdirectory that will
-contain all of the corresponding code. In our example, it will be
-`helloworld`. The new directory will be a python package, so you have
-to create an empty `__init__.py` file in that directory via, for
-example, `touch zerver/webhooks/helloworld/__init__.py`.
-
-## Step 2: Create main webhook code
-
-The majority of the code for your new integration will be in a single
-python file, `zerver/webhooks/mywebhook/view.py`.
-
-The Hello World integration is in `zerver/webhooks/helloworld/view.py`:
-
-```python
-from django.http import HttpRequest, HttpResponse
-
-from zerver.decorator import webhook_view
-from zerver.lib.response import json_success
-from zerver.lib.typed_endpoint import JsonBodyPayload, typed_endpoint
-from zerver.lib.validator import WildValue, check_string
-from zerver.lib.webhooks.common import check_send_webhook_message
-from zerver.models import UserProfile
-
-
-@webhook_view("HelloWorld")
-@typed_endpoint
-def api_helloworld_webhook(
-    request: HttpRequest,
-    user_profile: UserProfile,
-    *,
-    payload: JsonBodyPayload[WildValue],
-) -> HttpResponse:
-    # construct the body of the message
-    body = "Hello! I am happy to be here! :smile:"
-
-    # try to add the Wikipedia article of the day
-    body_template = (
-        "\nThe Wikipedia featured article for today is **[{featured_title}]({featured_url})**"
-    )
-    body += body_template.format(
-        featured_title=payload["featured_title"].tame(check_string),
-        featured_url=payload["featured_url"].tame(check_string),
-    )
-
-    topic = "Hello World"
-
-    # send the message
-    check_send_webhook_message(request, user_profile, topic, body)
-
-    return json_success(request)
-```
-
-The above code imports the required functions and defines the main webhook
-function `api_helloworld_webhook`, decorating it with `webhook_view` and
-`typed_endpoint`. The `typed_endpoint` decorator allows you to
-access request variables with `JsonBodyPayload()`. You can find more about `JsonBodyPayload` and request variables in [Writing views](
-https://zulip.readthedocs.io/en/latest/tutorials/writing-views.html#request-variables).
-
-You must pass the name of your integration to the
-`webhook_view` decorator; that name will be used to
-describe your integration in Zulip's analytics (e.g., the `/stats`
-page). Here we have used `HelloWorld`. To be consistent with other
-integrations, use the name of the product you are integrating in camel
-case, spelled as the product spells its own name (except always first
-letter upper-case).
-
-The `webhook_view` decorator indicates that the 3rd party service will
-send the authorization as an API key in the query parameters. If your service uses
-HTTP basic authentication, you would instead use the `authenticated_rest_api_view`
-decorator.
-
-You should name your webhook function as such
-`api_webhookname_webhook` where `webhookname` is the name of your
-integration and is always lower-case.
-
-At minimum, the webhook function must accept `request` (Django
-[HttpRequest](https://docs.djangoproject.com/en/5.0/ref/request-response/#django.http.HttpRequest)
-object), and `user_profile` (Zulip's user object). You may also want to
-define additional parameters using the `typed_endpoint` decorator.
-
-In the example above, we have defined `payload` which is populated
-from the body of the http request, `stream` with a default of `test`
-(available by default in the Zulip development environment), and
-`topic` with a default of `Hello World`. If your webhook uses a custom channel,
-it must exist before a message can be created in it. (See
-[Step 4: Create automated tests](#step-5-create-automated-tests) for how to handle this in tests.)
-
-The line that begins `# type` is a mypy type annotation. See [this
-page](https://zulip.readthedocs.io/en/latest/testing/mypy.html) for details about
-how to properly annotate your webhook functions.
-
-In the body of the function we define the body of the message as `Hello! I am
-happy to be here! :smile:`. The `:smile:` indicates an emoji. Then we append a
-link to the Wikipedia article of the day as provided by the json payload.
-
-* Sometimes, it might occur that a json payload does not contain all required keys your
-  integration checks for. In such a case, any `KeyError` thrown is handled by the server
-  backend and will create an appropriate response.
-
-Then we send a message with `check_send_webhook_message`, which will
-validate the message and do the following:
-
-* Send a public (channel) message if the `stream` query parameter is
-  specified in the webhook URL.
-* If the `stream` query parameter isn't specified, it will send a direct
-  message to the owner of the webhook bot.
-
-Finally, we return a 200 http status with a JSON format success message via
-`json_success(request)`.
-
-## Step 3: Create an API endpoint for the webhook
-
-In order for an incoming webhook to be externally available, it must be mapped
-to a URL. This is done in `zerver/lib/integrations.py`.
-
-Look for the lines beginning with:
-
-```python
-WEBHOOK_INTEGRATIONS: List[WebhookIntegration] = [
-```
-
-And you'll find the entry for Hello World:
-
-```python
-  WebhookIntegration("helloworld", ["misc"], display_name="Hello World"),
-```
-
-This tells the Zulip API to call the `api_helloworld_webhook` function in
-`zerver/webhooks/helloworld/view.py` when it receives a request at
-`/api/v1/external/helloworld`.
-
-This line also tells Zulip to generate an entry for Hello World on the Zulip
-integrations page using `static/images/integrations/logos/helloworld.svg` as its
-icon. The second positional argument defines a list of categories for the
-integration.
-
-At this point, if you're following along and/or writing your own Hello World
-webhook, you have written enough code to test your integration. There are three
-tools which you can use to test your webhook - 2 command line tools and a GUI.
-
-### Webhooks requiring custom configuration
-
-In rare cases, it's necessary for an incoming webhook to require
-additional user configuration beyond what is specified in the post
-URL.  The typical use case for this is APIs like the Stripe API that
-require clients to do a callback to get details beyond an opaque
-object ID that one would want to include in a Zulip notification.
-
-These configuration options are declared as follows:
-
-```python
-    WebhookIntegration('helloworld', ['misc'], display_name='Hello World',
-                       config_options=[('HelloWorld API key', 'hw_api_key', check_string)])
-```
-
-`config_options` is a list describing the parameters the user should
-configure:
-    1. A user-facing string describing the field to display to users.
-    2. The field name you'll use to access this from your `view.py` function.
-    3. A Validator, used to verify the input is valid.
-
-Common validators are available in `zerver/lib/validators.py`.
-
-## Step 4: Manually testing the webhook
-
-For either one of the command line tools, first, you'll need to get an
-API key from the **Bots** section of your Zulip user's **Personal
-settings**. To test the webhook, you'll need to [create a
-bot](https://zulip.com/help/add-a-bot-or-integration) with the
-**Incoming webhook** type. Replace `<api_key>` with your bot's API key
-in the examples presented below! This is how Zulip knows that the
-request was made by an authorized user.
-
-### Curl
-
-Using curl:
-```bash
-curl -X POST -H "Content-Type: application/json" -d '{ "featured_title":"Marilyn Monroe", "featured_url":"https://en.wikipedia.org/wiki/Marilyn_Monroe" }' http://localhost:9991/api/v1/external/helloworld\?api_key\=<api_key>
-```
-
-After running the above command, you should see something similar to:
-
-```json
-{"msg":"","result":"success"}
-```
-
-### Management command: send_webhook_fixture_message
-
-Using `manage.py` from within the Zulip development environment:
-
-```console
-(zulip-server) vagrant@vagrant:/srv/zulip$
-./manage.py send_webhook_fixture_message \
-    --fixture=zerver/webhooks/helloworld/fixtures/hello.json \
-    '--url=http://localhost:9991/api/v1/external/helloworld?api_key=<api_key>'
-```
-
-After running the above command, you should see something similar to:
-
-```
-2016-07-07 15:06:59,187 INFO     127.0.0.1       POST    200 143ms (mem: 6ms/13) (md: 43ms/1) (db: 20ms/9q) (+start: 147ms) /api/v1/external/helloworld (helloworld-bot@zulip.com via ZulipHelloWorldWebhook)
-```
-
-Some webhooks require custom HTTP headers, which can be passed using
-`./manage.py send_webhook_fixture_message --custom-headers`.  For
-example:
-
-    --custom-headers='{"X-Custom-Header": "value"}'
-
-The format is a JSON dictionary, so make sure that the header names do
-not contain any spaces in them and that you use the precise quoting
-approach shown above.
-
-For more information about `manage.py` command-line tools in Zulip, see
-the [management commands][management-commands] documentation.
-
-[management-commands]: https://zulip.readthedocs.io/en/latest/production/management-commands.html
-
-### Integrations Dev Panel
-This is the GUI tool.
-
-{start_tabs}
-
-1. Run `./tools/run-dev` then go to http://localhost:9991/devtools/integrations/.
-
-1. Set the following mandatory fields:
-**Bot** - Any incoming webhook bot.
-**Integration** - One of the integrations.
-**Fixture** - Though not mandatory, it's recommended that you select one and then tweak it if necessary.
-The remaining fields are optional, and the URL will automatically be generated.
-
-1. Click **Send**!
-
-{end_tabs}
-
-By opening Zulip in one tab and then this tool in another, you can quickly tweak
-your code and send sample messages for many different test fixtures.
-
-Note: Custom HTTP Headers must be entered as a JSON dictionary, if you want to use any in the first place that is.
-Feel free to use 4-spaces as tabs for indentation if you'd like!
-
-Your sample notification may look like:
-
-<img class="screenshot" src="/static/images/api/helloworld-webhook.png" alt="screenshot" />
-
-
-
-## Step 5: Create automated tests
-
-Every webhook integration should have a corresponding test file:
-`zerver/webhooks/mywebhook/tests.py`.
-
-The Hello World integration's tests are in `zerver/webhooks/helloworld/tests.py`
-
-You should name the class `<WebhookName>HookTests` and have it inherit from
-the base class `WebhookTestCase`. For our HelloWorld webhook, we name the test
-class `HelloWorldHookTests`:
-
-```python
-class HelloWorldHookTests(WebhookTestCase):
-    CHANNEL_NAME = "test"
-    URL_TEMPLATE = "/api/v1/external/helloworld?&api_key={api_key}&stream={stream}"
-    DIRECT_MESSAGE_URL_TEMPLATE = "/api/v1/external/helloworld?&api_key={api_key}"
-    WEBHOOK_DIR_NAME = "helloworld"
-
-    # Note: Include a test function per each distinct message condition your integration supports
-    def test_hello_message(self) -> None:
-        expected_topic = "Hello World"
-        expected_message = "Hello! I am happy to be here! :smile:\nThe Wikipedia featured article for today is **[Marilyn Monroe](https://en.wikipedia.org/wiki/Marilyn_Monroe)**"
-
-        # use fixture named helloworld_hello
-        self.check_webhook(
-            "hello",
-            expected_topic,
-            expected_message,
-            content_type="application/x-www-form-urlencoded",
-        )
-```
-
-In the above example, `CHANNEL_NAME`, `URL_TEMPLATE`, and `WEBHOOK_DIR_NAME` refer
-to class attributes from the base class, `WebhookTestCase`. These are needed by
-the helper function `check_webhook` to determine how to execute
-your test. `CHANNEL_NAME` should be set to your default channel. If it doesn't exist,
-`check_webhook` will create it while executing your test.
-
-If your test expects a channel name from a test fixture, the value in the fixture
-and the value you set for `CHANNEL_NAME` must match. The test helpers use `CHANNEL_NAME`
-to create the destination channel, and then create the message to send using the
-value from the fixture. If these don't match, the test will fail.
-
-`URL_TEMPLATE` defines how the test runner will call your incoming webhook, in the same way
- you would provide a webhook URL to the 3rd party service. `api_key={api_key}` says
-that an API key is expected.
-
-When writing tests for your webhook, you'll want to include one test function
-(and corresponding fixture) per each distinct message condition that your
-integration supports.
-
-If, for example, we added support for sending a goodbye message to our `Hello
-World` webhook, we would add another test function to `HelloWorldHookTests`
-class called something like `test_goodbye_message`:
-
-```python
-    def test_goodbye_message(self) -> None:
-        expected_topic = "Hello World"
-        expected_message = "Hello! I am happy to be here! :smile:\nThe Wikipedia featured article for today is **[Goodbye](https://en.wikipedia.org/wiki/Goodbye)**"
-
-        # use fixture named helloworld_goodbye
-        self.check_webhook(
-            "goodbye",
-            expected_topic,
-            expected_message,
-            content_type="application/x-www-form-urlencoded",
-        )
-```
-
-As well as a new fixture `goodbye.json` in
-`zerver/webhooks/helloworld/fixtures/`:
-
-```json
-{
-  "featured_title":"Goodbye",
-  "featured_url":"https://en.wikipedia.org/wiki/Goodbye",
-}
-```
-
-Also consider if your integration should have negative tests, a test where the
-data from the test fixture should result in an error. For details see
-[Negative tests](#negative-tests), below.
-
-Once you have written some tests, you can run just these new tests from within
-the Zulip development environment with this command:
-
-```console
-(zulip-server) vagrant@vagrant:/srv/zulip$
-./tools/test-backend zerver/webhooks/helloworld
-```
-
-(Note: You must run the tests from the top level of your development directory.
-The standard location in a Vagrant environment is `/srv/zulip`. If you are not
-using Vagrant, use the directory where you have your development environment.)
-
-You will see some script output and if all the tests have passed, you will see:
-
-```console
-Running zerver.webhooks.helloworld.tests.HelloWorldHookTests.test_goodbye_message
-Running zerver.webhooks.helloworld.tests.HelloWorldHookTests.test_hello_message
-DONE!
-```
-
-## Step 6: Create documentation
-
-Next, we add end-user documentation for our integration.  You
-can see the existing examples at <https://zulip.com/integrations>
-or by accessing `/integrations` in your Zulip development environment.
-
-There are two parts to the end-user documentation on this page.
-
-The first is the lozenge in the grid of integrations, showing your
-integration logo and name, which links to the full documentation.
-This is generated automatically once you've registered the integration
-in `WEBHOOK_INTEGRATIONS` in `zerver/lib/integrations.py`, and supports
-some customization via options to the `WebhookIntegration` class.
-
-Second, you need to write the actual documentation content in
-`zerver/webhooks/mywebhook/doc.md`.
-
-```md
-Learn how Zulip integrations work with this simple Hello World example!
-
-1.  The Hello World webhook will use the `test` channel, which is created
-    by default in the Zulip development environment. If you are running
-    Zulip in production, you should make sure that this channel exists.
-
-1. {!create-an-incoming-webhook.md!}
-
-1. {!generate-webhook-url-basic.md!}
-
-1.  To trigger a notification using this example webhook, you can use
-    `send_webhook_fixture_message` from a [Zulip development
-    environment](https://zulip.readthedocs.io/en/latest/development/overview.html):
-
-    ```
-        (zulip-server) vagrant@vagrant:/srv/zulip$
-        ./manage.py send_webhook_fixture_message \
-        > --fixture=zerver/tests/fixtures/helloworld/hello.json \
-        > '--url=http://localhost:9991/api/v1/external/helloworld?api_key=abcdefgh&stream=stream%20name;'
-    ```
-
-    Or, use curl:
-
-    ```
-    curl -X POST -H "Content-Type: application/json" -d '{ "featured_title":"Marilyn Monroe", "featured_url":"https://en.wikipedia.org/wiki/Marilyn_Monroe" }' http://localhost:9991/api/v1/external/helloworld\?api_key=abcdefgh&stream=stream%20name;
-    ```
-
-{!congrats.md!}
-
-![Hello World integration](/static/images/integrations/helloworld/001.png)
-
-```
-
-`{!create-an-incoming-webhook.md!}` and `{!congrats.md!}` are examples of
-a Markdown macro. Zulip has a macro-based Markdown/Jinja2 framework that
-includes macros for common instructions in Zulip's webhooks/integrations
-documentation.
-
-See
-[our guide on documenting an integration][integration-docs-guide]
-for further details, including how to easily create the message
-screenshot. Mostly you should plan on templating off an existing guide, like
-[this one](https://raw.githubusercontent.com/zulip/zulip/main/zerver/webhooks/github/doc.md).
-
-[integration-docs-guide]: https://zulip.readthedocs.io/en/latest/documentation/integrations.html
-
-## Step 7: Preparing a pull request to zulip/zulip
-
-When you have finished your webhook integration, follow these guidelines before
-pushing the code to your fork and submitting a pull request to zulip/zulip:
-
-- Run tests including linters and ensure you have addressed any issues they
-  report. See [Testing](https://zulip.readthedocs.io/en/latest/testing/testing.html)
-  and [Linters](https://zulip.readthedocs.io/en/latest/testing/linters.html) for details.
-- Read through [Code styles and conventions](
-  https://zulip.readthedocs.io/en/latest/contributing/code-style.html) and take a look
-  through your code to double-check that you've followed Zulip's guidelines.
-- Take a look at your Git history to ensure your commits have been clear and
-  logical (see [Commit discipline](
-  https://zulip.readthedocs.io/en/latest/contributing/commit-discipline.html) for tips). If not,
-  consider revising them with `git rebase --interactive`. For most incoming webhooks,
-  you'll want to squash your changes into a single commit and include a good,
-  clear commit message.
-
-If you would like feedback on your integration as you go, feel free to post a
-message on the [public Zulip instance](https://chat.zulip.org/#narrow/channel/integrations).
-You can also create a [draft pull request](
-https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-pull-requests#draft-pull-requests) while you
-are still working on your integration. See the
-[Git guide](https://zulip.readthedocs.io/en/latest/git/pull-requests.html#create-a-pull-request)
-for more on Zulip's pull request process.
-
-## Advanced topics
-
-More complex implementation or testing needs may require additional code, beyond
-what the standard helper functions provide. This section discusses some of
-these situations.
-
-### Negative tests
-
-A negative test is one that should result in an error, such as incorrect data.
-The helper functions may interpret this as a test failure, when it should instead
-be a successful test of an error condition. To correctly test these cases, you
-must explicitly code your test's execution (using other helpers, as needed)
-rather than call the usual helper function.
-
-Here is an example from the WordPress integration:
-
-```python
-def test_unknown_action_no_data(self) -> None:
-    # Mimic check_webhook() to manually execute a negative test.
-    # Otherwise its call to send_webhook_payload() would assert on the non-success
-    # we are testing. The value of result is the error message the webhook should
-    # return if no params are sent. The fixture for this test is an empty file.
-
-    # subscribe to the target channel
-    self.subscribe(self.test_user, self.CHANNEL_NAME)
-
-    # post to the webhook url
-    post_params = {'stream_name': self.CHANNEL_NAME,
-                   'content_type': 'application/x-www-form-urlencoded'}
-    result = self.client_post(self.url, 'unknown_action', **post_params)
-
-    # check that we got the expected error message
-    self.assert_json_error(result, "Unknown WordPress webhook action: WordPress action")
-```
-
-In a normal test, `check_webhook` would handle all the setup
-and then check that the incoming webhook's response matches the expected result. If
-the webhook returns an error, the test fails. Instead, explicitly do the
-setup it would have done, and check the result yourself.
-
-Here, `subscribe_to_stream` is a test helper that uses `TEST_USER_EMAIL` and
-`CHANNEL_NAME` (attributes from the base class) to register the user to receive
-messages in the given channel. If the channel doesn't exist, it creates it.
-
-`client_post`, another helper, performs the HTTP POST that calls the incoming
-webhook. As long as `self.url` is correct, you don't need to construct the webhook
-URL yourself. (In most cases, it is.)
-
-`assert_json_error` then checks if the result matches the expected error.
-If you had used `check_webhook`, it would have called
-`send_webhook_payload`, which checks the result with `assert_json_success`.
-
-### Custom query parameters
-
-Custom arguments passed in URL query parameters work as expected in the webhook
-code, but require special handling in tests.
-
-For example, here is the definition of a webhook function that gets both `stream`
-and `topic` from the query parameters:
-
-```python
-@typed_endpoint
-def api_querytest_webhook(request: HttpRequest, user_profile: UserProfile,
-                          payload: Annotated[str, ApiParamConfig(argument_type_is_body=True)],
-                          stream: str = "test",
-                          topic: str= "Default Alert":
-```
-
-In actual use, you might configure the 3rd party service to call your Zulip
-integration with a URL like this:
-
-```
-http://myhost/api/v1/external/querytest?api_key=abcdefgh&stream=alerts&topic=queries
-```
-
-It provides values for `stream` and `topic`, and the webhook can get those
-using `@typed_endpoint` without any special handling. How does this work in a test?
-
-The new attribute `TOPIC` exists only in our class so far. In order to
-construct a URL with a query parameter for `topic`, you can pass the
-attribute `TOPIC` as a keyword argument to `build_webhook_url`, like so:
-
-```python
-class QuerytestHookTests(WebhookTestCase):
-
-    CHANNEL_NAME = 'querytest'
-    TOPIC = "Default topic"
-    URL_TEMPLATE = "/api/v1/external/querytest?api_key={api_key}&stream={stream}"
-    FIXTURE_DIR_NAME = 'querytest'
-
-    def test_querytest_test_one(self) -> None:
-        # construct the URL used for this test
-        self.TOPIC = "Query test"
-        self.url = self.build_webhook_url(topic=self.TOPIC)
-
-        # define the expected message contents
-        expected_topic = "Query test"
-        expected_message = "This is a test of custom query parameters."
-
-        self.check_webhook('test_one', expected_topic, expected_message,
-                                          content_type="application/x-www-form-urlencoded")
-```
-
-You can also override `get_body` or `get_payload` if your test data
-needs to be constructed in an unusual way.
-
-For more, see the definition for the base class, `WebhookTestCase`
-in `zerver/lib/test_classes.py`, or just grep for examples.
-
-
-### Custom HTTP event-type headers
-
-Some third-party services set a custom HTTP header to indicate the event type that
-generates a particular payload. To extract such headers, we recommend using the
-`validate_extract_webhook_http_header` function in `zerver/lib/webhooks/common.py`,
-like so:
-
-```python
-event = validate_extract_webhook_http_header(request, header, integration_name)
-```
-
-`request` is the `HttpRequest` object passed to your main webhook function. `header`
-is the name of the custom header you'd like to extract, such as `X-Event-Key`, and
-`integration_name` is the name of the third-party service in question, such as
-`GitHub`.
-
-Because such headers are how some integrations indicate the event types of their
-payloads, the absence of such a header usually indicates a configuration
-issue, where one either entered the URL for a different integration, or happens to
-be running an older version of the integration that doesn't set that header.
-
-If the requisite header is missing, this function sends a direct message to the
-owner of the webhook bot, notifying them of the missing header.
-
-### Handling unexpected webhook event types
-
-Many third-party services have dozens of different event types. In
-some cases, we may choose to explicitly ignore specific events. In
-other cases, there may be events that are new or events that we don't
-know about. In such cases, we recommend raising
-`UnsupportedWebhookEventTypeError` (found in `zerver/lib/exceptions.py`),
-with a string describing the unsupported event type, like so:
-
-```
-raise UnsupportedWebhookEventTypeError(event_type)
-```

-# The Zulip API
-
-Zulip's APIs allow you to integrate other services with Zulip.  This
-guide should help you find the API you need:
-
-* First, check if the tool you'd like to integrate with Zulip
-  [already has a native integration](/integrations/).
-* Next, check if [Zapier](https://zapier.com/apps) or
-  [IFTTT](https://ifttt.com/search) has an integration.
-  [Zulip's Zapier integration](/integrations/doc/zapier) and
-  [Zulip's IFTTT integration](/integrations/doc/ifttt) often allow
-  integrating a new service with Zulip without writing any code.
-* If you'd like to send content into Zulip, you can
-  [write a native incoming webhook integration](/api/incoming-webhooks-overview)
-  or use [Zulip's API for sending messages](/api/send-message).
-* If you're building an interactive bot that reacts to activity inside
-  Zulip, you'll want to look at Zulip's
-  [Python framework for interactive bots](/api/running-bots) or
-  [Zulip's real-time events API](/api/get-events).
-
-And if you still need to build your own integration with Zulip, check out
-the full [REST API](/api/rest), generally starting with
-[installing the API client bindings](/api/installation-instructions).
-
-In case you already know how you want to build your integration and you're
-just looking for an API key, we've got you covered [here](/api/api-keys).

-# Integrations overview
-
-Integrations let you connect Zulip with other products. For example, you can get
-notification messages in Zulip when an issue in your tracker is updated, or for
-alerts from your monitoring tool.
-
-Zulip offers [over 120 native integrations](/integrations/), which take
-advantage of Zulip's [topics](/help/introduction-to-topics) to organize
-notification messages. Additionally, thousands of integrations are available
-through [Zapier](https://zapier.com/apps) and [IFTTT](https://ifttt.com/search).
-You can also [connect any webhook designed to work with
-Slack](/integrations/doc/slack_incoming) to Zulip.
-
-If you don't find an integration you need, you can:
-
-- [Write your own integration](#write-your-own-integration). You can [submit a
-pull
-request](https://zulip.readthedocs.io/en/latest/contributing/reviewable-prs.html)
-to get your integration merged into the main Zulip repository.
-
-- [File an issue](https://github.com/zulip/zulip/issues/new/choose) to request
-  an integration (if it's a nice-to-have).
-
-- [Contact Zulip Sales](mailto:sales@zulip.com) to inquire about a custom
-  development contract.
-
-## Set up an integration
-
-### Native integrations
-
-{start_tabs}
-
-1. [Search Zulip's integrations](/integrations/) for the product you'd like to
-   connect to Zulip.
-
-1. Click on the card for the product, and follow the instructions on the page.
-
-{end_tabs}
-
-### Integrate via Zapier or IFTTT
-
-If you don't see a native Zulip integration, you can access thousands of
-additional integrations through [Zapier](https://zapier.com/apps) and
-[IFTTT](https://ifttt.com/search).
-
-{start_tabs}
-
-1. Search [Zapier](https://zapier.com/apps) or [IFTTT](https://ifttt.com/search)
-for the product you'd like to connect to Zulip.
-
-1. Follow the integration instructions for [Zapier](/integrations/doc/zapier) or
-   [IFTTT](/integrations/doc/ifttt).
-
-{end_tabs}
-
-### Integrate via Slack-compatible webhook API
-
-Zulip can process incoming webhook messages written to work with [Slack's
-webhook API](https://api.slack.com/messaging/webhooks). This makes it easy to
-quickly move your integrations when [migrating your
-organization](/help/import-from-slack) from Slack to Zulip, or integrate any
-product that has a Slack webhook integration with Zulip .
-
-!!! warn ""
-
-     **Note:** In the long term, the recommended approach is to use
-     Zulip's native integrations, which take advantage of Zulip's topics.
-     There may also be some quirks when Slack's formatting system is
-     translated into Zulip's.
-
-{start_tabs}
-
-1. [Create a bot](/help/add-a-bot-or-integration) for the Slack-compatible
-   webhook. Make sure that you select **Incoming webhook** as the **Bot type**.
-
-1. Decide where to send Slack-compatible webhook notifications, and [generate
-   the integration URL](https://zulip.com/help/generate-integration-url).
-
-1. Use the generated URL anywhere you would use a Slack webhook.
-
-{end_tabs}
-
-### Integrate via email
-
-If the product you'd like to integrate can send email notifications, you can
-[send those emails to a Zulip channel](/help/message-a-channel-by-email). The
-email subject will become the Zulip topic, and the email body will become the
-Zulip message.
-
-For example, you can configure your personal GitHub notifications to go to a
-Zulip channel rather than your email inbox. Notifications for each issue or pull
-request will be grouped into a single topic.
-
-## Write your own integration
-
-You can write your own Zulip integrations using the well-documented APIs below.
-For example, if your company develops software, you can create a custom
-integration to connect your product to Zulip.
-
-If you need help, best-effort community support is available in the [Zulip
-development community](https://zulip.com/development-community/). To inquire
-about options for custom development, [contact Zulip
-Sales](mailto:sales@zulip.com).
-
-### Sending content into Zulip
-
-* If the third-party service supports outgoing webhooks, you likely want to
-  build an [incoming webhook integration](/api/incoming-webhooks-overview).
-
-* If it doesn't, you may want to write a
-  [script or plugin integration](/api/non-webhook-integrations).
-
-* The [`zulip-send` tool](/api/send-message) makes it easy to send Zulip
-  messages from shell scripts.
-
-* Finally, you can
-  [send messages using Zulip's API](/api/send-message), with bindings for
-  Python, JavaScript and [other languages](/api/client-libraries).
-
-### Sending and receiving content
-
-* To react to activity inside Zulip, look at Zulip's
-  [Python framework for interactive bots](/api/running-bots) or
-  [Zulip's real-time events API](/api/get-events).
-
-* If what you want isn't covered by the above, check out the full
-  [REST API](/api/rest). The web, mobile, desktop, and terminal apps are
-  built on top of this API, so it can do anything a human user can do. Most
-  but not all of the endpoints are documented on this site; if you need
-  something that isn't there check out Zulip's
-  [REST endpoints](https://github.com/zulip/zulip/blob/main/zproject/urls.py).

-# Message formatting
-
-Zulip supports an extended version of Markdown for messages, as well as
-some HTML level special behavior. The Zulip help center article on [message
-formatting](/help/format-your-message-using-markdown) is the primary
-documentation for Zulip's markup features. This article is currently a
-changelog for updates to these features.
-
-The [render a message](/api/render-message) endpoint can be used to get
-the current HTML version of any Markdown syntax for message content.
-
-## Code blocks
-
-**Changes**: As of Zulip 4.0 (feature level 33), [code blocks][help-code]
-can have a `data-code-language` attribute attached to the outer HTML
-`div` element, which records the programming language that was selected
-for syntax highlighting. This field is used in the
-[playgrounds][help-playgrounds] feature for code blocks.
-
-## Global times
-
-**Changes**: In Zulip 3.0 (feature level 8), added [global time
-mentions][help-global-time] to supported Markdown message formatting
-features.
-
-## Links to channels, topics, and messages
-
-Zulip's markup supports special readable Markdown syntax for [linking
-to channels, topics, and messages](/help/link-to-a-message-or-conversation).
-
-Sample HTML formats are as follows:
-``` html
-<!-- Syntax: #**announce** -->
-<a class="stream" data-stream-id="9"
-  href="/#narrow/channel/9-announce">
- #announce
-</a>
-
-<!-- Syntax: #**announce>Zulip updates** -->
-<a class="stream-topic" data-stream-id="9"
-  href="/#narrow/channel/9-announce/topic/Zulip.20updates/with/214">
- #announce &gt; Zulip updates
-</a>
-
-<!-- Syntax: #**announce>Zulip updates**
-     Generated only if topic had no messages or the link was rendered
-     before Zulip 10.0 (feature level 347) -->
-<a class="stream-topic" data-stream-id="9"
-  href="/#narrow/channel/9-announce/topic/Zulip.20updates">
- #announce &gt; Zulip updates
-</a>
-
-<!-- Syntax: #**announce>Zulip updates@214** -->
-<a class="message-link"
-  href="/#narrow/channel/9-announce/topic/Zulip.20updates/near/214">
- #announce &gt; Zulip updates @ 💬
-</a>
-```
-
-The `near` and `with` operators are documented in more detail in the
-[search and URL documentation](/api/construct-narrow). When rendering
-topic links with the `with` operator, the code doing the rendering may
-pick the ID arbitrarily among messages accessible to the client and/or
-acting user at the time of rendering. Currently, the server chooses
-the message ID to use for `with` operators as the oldest message ID in
-the topic accessible to the user who wrote the message. In channels
-with protected history, this means the same Markdown syntax may be
-rendered differently for users who joined at different times.
-
-The older stream/topic link elements include a `data-stream-id`, which
-historically was used in order to display the current channel name if
-the channel had been renamed. That field is **deprecated**, because
-displaying an updated value for the most common forms of this syntax
-requires parsing the URL to get the topic to use anyway.
-
-When a topic is an empty string, it is replaced with
-`realm_empty_topic_display_name` found in the [`POST /register`](/api/register-queue)
-response and wrapped with the `<em>` tag.
-
-Sample HTML formats with `"realm_empty_topic_display_name": "general chat"`
-are as follows:
-```html
-<!-- Syntax: #**announce>** -->
-<a class="stream-topic" data-stream-id="9"
-  href="/#narrow/channel/9-announce/topic/with/214">
- #announce &gt; <em>general chat</em>
-</a>
-
-<!-- Syntax: #**announce>**
-     Generated only if topic had no messages or the link was rendered
-     before Zulip 10.0 (feature level 347) -->
-<a class="stream-topic" data-stream-id="9"
-  href="/#narrow/channel/9-announce/topic/">
- #announce &gt; <em>general chat</em>
-</a>
-
-<!-- Syntax: #**announce>@214** -->
-<a class="message-link"
-  href="/#narrow/channel/9-announce/topic//near/214">
- #announce &gt; <em>general chat</em> @ 💬
-</a>
-```
-
-**Changes**: Before Zulip 10.0 (feature level 347), the `with` field
-was never used in topic link URLs generated by the server; the markup
-currently used only for empty topics was used for all topic links.
-
-Before Zulip 10.0 (feature level 346), empty string
-was not a valid topic name in syntaxes for linking to topics and
-messages.
-
-In Zulip 10.0 (feature level 319), added Markdown syntax
-for linking to a specific message in a conversation. Declared the
-`data-stream-id` field to be deprecated as detailed above.
-
-## Image previews
-
-When a Zulip message is sent linking to an uploaded image, Zulip will
-generate an image preview element with the following format.
-
-``` html
-<div class="message_inline_image">
-    <a href="/user_uploads/path/to/image.png" title="image.png">
-        <img data-original-dimensions="1920x1080"
-          data-original-content-type="image/png"
-          src="/user_uploads/thumbnail/path/to/image.png/840x560.webp">
-    </a>
-</div>
-```
-
-If the server has not yet generated thumbnails for the image yet at
-the time the message is sent, the `img` element will be a temporary
-loading indicator image and have the `image-loading-placeholder`
-class, which clients can use to identify loading indicators and
-replace them with a more native loading indicator element if
-desired. For example:
-
-``` html
-<div class="message_inline_image">
-    <a href="/user_uploads/path/to/image.png" title="image.png">
-        <img class="image-loading-placeholder"
-          data-original-dimensions="1920x1080"
-          data-original-content-type="image/png"
-          src="/path/to/spinner.png">
-    </a>
-</div>
-```
-
-Once the server has a working thumbnail, such messages will be updated
-via an `update_message` event, with the `rendering_only: true` flag
-(telling clients not to adjust message edit history), with appropriate
-adjusted `rendered_content`. A client should process those events by
-just using the updated rendering. If thumbnailing failed, the same
-type of event will edit the message's rendered form to remove the
-image preview element, so no special client-side logic should be
-required to process such errors.
-
-Note that in the uncommon situation that the thumbnailing system is
-backlogged, an individual message containing multiple image previews
-may be re-rendered multiple times as each image finishes thumbnailing
-and triggers a message update.
-
-Clients are recommended to do the following when processing image
-previews:
-
-- Clients that would like to use the image's aspect ratio to lay out
-  one or more images in the message feed may use the
-  `data-original-dimensions` attribute, which is present even if the
-  image is a placeholder spinner.  This attribute encodes the
-  dimensions of the original image as `{width}x{height}`.  These
-  dimensions are for the image as rendered, _after_ any EXIF rotation
-  and mirroring has been applied.
-- If the client would like to control the thumbnail resolution used,
-  it can replace the final section of the URL (`840x560.webp` in the
-  example above) with the `name` of its preferred format from the set
-  of supported formats provided by the server in the
-  `server_thumbnail_formats` portion of the `register`
-  response. Clients should not make any assumptions about what format
-  the server will use as the "default" thumbnail resolution, as it may
-  change over time.
-- Download button type elements should provide the original image
-  (encoded via the `href` of the containing `a` tag).
-- The content-type of the original image is provided on a
-  `data-original-content-type` attribute, so clients can decide if
-  they are capable of rendering the original image.
-- For images whose formats which are not widely-accepted by browsers
-  (e.g., HEIC and TIFF), the image may contain a
-  `data-transcoded-image` attribute, which specifies a high-resolution
-  thumbnail format which clients may use instead of the original
-  image.
-- Lightbox elements for viewing an image should be designed to
-  immediately display any already-downloaded thumbnail while fetching
-  the original-quality image or an appropriate higher-quality
-  thumbnail from the server, to be transparently swapped in once it is
-  available. Clients that would like to size the lightbox based on the
-  size of the original image can use the `data-original-dimensions`
-  attribute, as described above.
-- Animated images will have a `data-animated` attribute on the `img`
-  tag. As detailed in `server_thumbnail_formats`, both animated and
-  still images are available for clients to use, depending on their
-  preference. See, for example, the [web setting][help-previews]
-  to control whether animated images are autoplayed in the message
-  feed.
-- Clients should not assume that the requested format is the format
-  that they will receive; in rare cases where the client has an
-  out-of-date list of `server_thumbnail_formats`, the server will
-  provide an approximation of the client's requested format.  Because
-  of this, clients should not assume that the pixel dimensions or file
-  format match what they requested.
-- No other processing of the URLs is recommended.
-
-**Changes**: In Zulip 10.0 (feature level 336), added
-`data-original-content-type` attribute to convey the type of the
-original image, and optional `data-transcoded-image` attribute for
-images with formats which are not widely supported by browsers.
-
-**Changes**: In Zulip 9.2 (feature levels 278-279, and 287+), added
-`data-original-dimensions` to the `image-loading-placeholder` spinner
-images, containing the dimensions of the original image.
-
-In Zulip 9.0 (feature level 276), added `data-original-dimensions`
-attribute to images that have been thumbnailed, containing the
-dimensions of the full-size version of the image. Thumbnailing itself
-was reintroduced at feature level 275.
-
-Previously, with the exception of Zulip servers that used the beta
-Thumbor-based implementation years ago, all image previews in Zulip
-messages were not thumbnailed; the `a` tag and the `img` tag would both
-point to the original image.
-
-Clients that correctly implement the current API should handle
-Thumbor-based older thumbnails correctly, as long as they do not
-assume that `data-original-dimensions` is present. Clients should not
-assume that messages sent prior to the introduction of thumbnailing
-have been re-rendered to use the new format or have thumbnails
-available.
-
-## Mentions and silent mentions
-
-Zulip markup supports [mentioning](/help/mention-a-user-or-group)
-users, user groups, and a few special "wildcard" mentions (the three
-spellings of a channel wildcard mention: `@**all**`, `@**everyone**`,
-`@**channel**` and the topic wildcard mention `@**topic**`).
-
-Mentions result in a message being highlighted for the target user(s),
-both in the UI and in notifications, and may also result in the target
-user(s) following the conversation, [depending on their
-settings](/help/follow-a-topic#follow-topics-where-you-are-mentioned).
-
-Silent mentions of users or groups have none of those side effects,
-but nonetheless uniquely identify the user or group
-identified. (There's no such thing as a silent wildcard mention).
-
-Permissions for mentioning users work as follows:
-
-- Any user can mention any other user, though mentions by [muted
-users](/help/mute-a-user) are automatically marked as read and thus do
-not trigger notifications or otherwise get highlighted like unread
-mentions.
-
-- Wildcard mentions are permitted except where [organization-level
-restrictions](/help/restrict-wildcard-mentions) apply.
-
-- User groups can be mentioned if and only if the acting user is in
-the `can_mention_group` group for that group. All user groups can be
-silently mentioned by any user.
-
-- System groups, when (silently) mentioned, should be displayed using
-their description, not their `role:nobody` style API names; see the
-main [system group
-documentation](/api/group-setting-values#system-groups) for
-details. System groups can only be silently mentioned right now,
-because they happen to all use the empty `Nobody` group for
-`can_mention_group`; clients should just use `can_mention_group` to
-determine which groups to offer in typeahead in similar contexts.
-
-- Requests to send or edit a message that are impermissible due to
-including a mention where the acting user does not have permission to
-mention the target will return an error. Mention syntax that does not
-correspond to a real user or group is ignored.
-
-Sample markup for `@**Example User**`:
-
-``` html
-<span class="user-mention" data-user-id="31">@Example User</span>
-```
-
-Sample markup for `@_**Example User**`:
-
-``` html
-<span class="user-mention silent" data-user-id="31">Example User</span>

-When processing mentions, clients should look up the user or group
-referenced by ID, and update the textual name for the mention to the
-current name for the user or group with that ID. Note that for system
-groups, this requires special logic to look up the user-facing name
-for that group; see [system
-groups](/api/group-setting-values#system-groups) for details.
